Problems solved by technology

[0006] For the structure that can realize the rotation of the pliers head by the rotation of the pliers rod, when the pliers head of the grasping forceps has clamped the tissue by closing, it is difficult to avoid when the pliers rod can rotate at this time. Improper operation by medical staff, or unconscious operation errors, the forceps head that has clamped and fixed the tissue produces a rotating motion and pulls the tissue, resulting in unexpected damage to the tissue

Embodiment 1

[0071] see Figure 1 to Figure 16 As shown, the present embodiment provides a puncture forceps, comprising: a body 11, a pliers rod 1 matched with the body 11, and a movable handle 12; Rotation fit, so that the movable handle 12 can rotate relative to the device body 11 under the pinching action of the hand of the medical staff. The pliers rod 1 here has a hollow accommodating cavity passing through both ends in the axial direction, and a pliers body 50 adapted to move axially relative to the pliers rod 1 runs through the accommodating cavity; and one end of the pliers rod 1 away from the body 11 It has a cone tip 51; one end of the pliers body 50 adapted to protrude from the cone tip 51 is provided with a pair of pliers wings 52 suitable for opening.

[0072] Considering the convenience of processing and the smoothness of use, the pair of pliers wings 52 and the pliers body 50 of this embodiment are integrally processed and formed.

[0073] It should be noted that, in an op...

Embodiment 2

[0095] see Figure 7 to Figure 12 As shown, on the basis of the puncture forceps of the embodiment 1, the puncture forceps of the present embodiment also includes a drive structure for the axial movement of the pliers rod 1 that is matched with the pliers rod 1, including: a push rod 21, a movable mechanism arranged on the push rod 21, The pin 26 , the locking piece suitable for cooperating with the movable pin 26 , and the spring body 55 sleeved on the pliers rod 1 .

[0096] Next, first, putter 21:

[0097] Push rod 21, which is suitable for pushing the pliers rod 1 of the medical device; one end of the push rod 21 is provided with a toggle for pushing the pliers rod 1, and the end of the push rod 21 away from the push head is hinged with the movable handle 12 of the medical device Cooperate. The push rod 21 is rotationally fitted with the device body 11 through the first connecting pin shaft 22, that is to say, the driving action on the push rod 21 can be generated during...

Embodiment 3

[0116] see Figure 7 to Figure 12 As shown, on the basis of the puncture forceps in Embodiment 2, the driving structure of the puncture forceps provided in this embodiment further includes a driving rod 42 connected to the side end surface of each locking piece 30 away from the forceps rod 1 ; And on the side wall of the body 11 is provided with a waist-shaped movable groove 43 suitable for the driving rod 42 to pass through; Here, the setting of the shifting block 45 is convenient for the hand of the medical staff to exert force on the shifting lever 42 .

[0117] Because in the process that the movable pin 26 rotates along with the push rod 21, the locking teeth contact the movable pin 26 before the locking opening 31, that is to say, the locking opening 31 corresponds to the movable pin 26 relative to the locking teeth. The rotation range is larger, and for the locking port 31, it corresponds to the special situation that a pair of pincer wings 52 are completely folded in ...

Abstract

The invention discloses puncture forceps and a use method thereof. The puncture forceps comprise a device body, a forceps rod and a movable handle mathced with the device body; the forceps rod is provided with a hollow containing cavity penetrating through the two axial ends, and a forceps body suitable for axially moving relative to the forceps rod penetrates through the containing cavity; one end of the forceps rod away from the device body is provided with a conical tip; a pair of forceps wings suitable for being opened is arranged at the end, suitable for extending out of the conical tip, of the forceps body. The puncture forceps provided by the invention can be used to complete establishment of a channel and clamping of tissue at the same time through one instrument.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a puncture forceps and a use method thereof. Background technique [0002] In minimally invasive laparoscopic surgery, it is necessary to use a puncture device to establish a channel suitable for such as but not limited to forceps, tweezers, etc., and then insert the forceps or tweezers into the above-mentioned channel to perform such as but not limited to Operations such as clipping, cutting or electrocoagulation to stop bleeding. On the one hand, this mode of operation is cumbersome, and on the other hand, it will also cause an increase in the use cost of the device. [0003] Furthermore, in minimally invasive laparoscopic surgery, it is necessary to use a variety of instruments whose heads can be opened and closed, such as tweezers, pliers, etc.; the pliers include separating forceps and grasping forceps. The present invention is an example of grasping forceps, g...
