Problems solved by technology

However, the ultrasonic scalpel currently on the market is a non-detachable structure, which cannot be restored once it is disassembled, and due to the narrow and long structural design characteristics of the knife bar assembly (the longest knife bar can reach 45cm), it has the following shortcomings: 1. After the operation, tissue debris, fat, interstitial fluid, blood, etc. have often penetrated into the narrow and deep cannula cavity of the ultrasonic scalpel, forming scabs on the inner wall of the cavity and the knife rod. In the current situation where the ultrasonic scalpel is not removable Under these conditions, these scabs attached to the inside of the blade are not only difficult to clean, but also impossible to clean, and cannot be thoroughly cleaned and disinfected.
In addition, the pollutants in the inner cavity of the traditional ultrasonic scalpel will reduce the life of the knife rod, reduce the cutting and coagulation effect of the knife, prolong the operation time, and cannot be reused
Therefore, the ultrasonic scalpels currently on the market are all used as disposable surgical instruments, and repeated use is prohibited.
At the same time, its high price is a heavy burden for patients and hospitals

Embodiment 1

[0075] A kind of reusable ultrasonic scalpel that present embodiment relates to, as figure 1 , figure 2 , image 3 , Figure 4b , Figure 5b with Figure 10 As shown, the ultrasonic scalpel includes a knife 1, a knife bar assembly 2, a rotating handle 3, a force limiting device 210, a gun handle assembly 4, a transducer and a host 6, the knife 1, the knife bar assembly 2, The rotating handle 3, the force limiting device 210, the gun handle assembly 4, the transducer and the host machine 6 are sequentially connected; Silicone ring 204 on the rod 203;

[0076] The silicone ring 204 is in interference fit with the inner sleeve 202 .

[0077] The transducer is an ultrasonic transducer 5 .

[0078] The cutter 1 includes a cutter head 101 and a pliers head 102;

[0079] The cutter head 101 and the pliers head 102 are connected by rivets.

[0080] The gun handle assembly 4 includes a pressing handle 401, a pressing push rod 402 and an activation key 403 button;

[0081] Th...

Embodiment 2

[0101] A kind of reusable ultrasonic scalpel that this embodiment relates to, the structure is basically the same as embodiment 1, only difference is:

[0102] Such as Figure 6a with Figure 6b As shown, the knife rod assembly 2 also includes a pressure sensor 205 for real-time detection of the pressure between the silicone ring 204 and the inner sleeve 202 and an alarm connected to the pressure sensor; the pressure sensor 205 Sandwiched between the silicone ring 204 and the inner sleeve 202, the alarm is set in the host 6; when the pressure between the silicone ring 204 and the inner sleeve 202 is less than the set value , the alarm sends out an alarm, and the user replaces the cutter 1 or sleeve through the alarm.

Embodiment 3

[0104] A kind of reusable ultrasonic scalpel that this embodiment relates to, the structure is basically the same as embodiment 1, only difference is:

[0105] Such as Figure 7 , Figure 7a~Figure 7c As shown, the inner sleeve 202 is divided into the inner sleeve 2022 at the pincer head end and the inner sleeve 2021 at the rotating handle end; the outer sleeve 201 is divided into the outer sleeve 2012 at the pincer head end and the outer sleeve 2011 at the rotating handle end; The inner casing 2022 at the pliers head end and the inner casing 2021 at the rotating handle end adopt an L-shaped snap-fit ​​structure, and the outer casing 2012 at the pliers head end and the outer casing 2011 at the rotating handle end adopt an L-shaped locking structure. Clamping structure clamping; when the inner sleeve 2022 of the pliers end and the outer sleeve 2012 of the pliers end are polluted, the inner sleeve 2022 of the pliers end and the outer sleeve 2012 of the pliers end can be replace...

Abstract

The invention relates to a reusable ultrasonic scalpel, and belongs to the field of minimally invasive medical instruments. The ultrasonic scalpel comprises a scalpel tool, a scalpel rod assembly anda functional assembly; the scalpel tool, the scalpel rod assembly and the functional assembly are sequentially connected; the scalpel rod assembly comprises a scalpel rod, an inner sleeve and an outersleeve, and the inner sleeve and the outer sleeve sequentially sleeve the scalpel rod from inside to outside; the inner sleeve is divided into a jaw end inner sleeve and a rotating handle end inner sleeve, and the outer sleeve is divided into a jaw end outer sleeve and a rotating handle end outer sleeve; the jaw end inner sleeve is clamped to the rotating handle end inner sleeve through an L-shaped clamping structure, and the jaw end outer sleeve is clamped to the rotating handle end outer sleeve through an L-shaped clamping structure. The reusable ultrasonic scalpel has the advantages of being easy to clean, economical and capable of being repeatedly used after high-pressure sterilization, and the waste of medical instruments is reduced.

Description

technical field [0001] The invention belongs to the field of minimally invasive medical instruments. Specifically relates to a reusable ultrasonic scalpel. Background technique [0002] The scalpel is an indispensable tool in surgical medical instruments. The scalpel is divided into blades and handles. The blade is disposable and the handle is reusable. However, the traditional scalpel has the disadvantages of excessive surgical bleeding and slow postoperative recovery. In recent years, the ultrasonic scalpel has been widely promoted because of its advantages of less surgical bleeding and fast postoperative recovery. [0003] Ultrasonic scalpels have advantages that ordinary scalpels do not have. It can complete coagulation and cutting simultaneously, and can close blood vessels less than or equal to 5mm in good effect, reducing the risk of intraoperative bleeding; it combines grasping, separation, cutting, and coagulation in one body, reducing the configuration of surgic...
