Single-hole multichannel rotatable operating device of laparoscope

Abstract

The invention discloses a single-hole multichannel rotatable operating device of a laparoscope. The single-hole multichannel rotatable operating device comprises an expansion cylinder and is characterized in that a surgery channel is formed in the middle of the expansion cylinder, the front portion of the expansion cylinder is small, the rear portion of the expansion cylinder is large, the external circle of the expansion cylinder is in arc-shaped transition from front to rear, the front end of the external circle of the expansion cylinder is provided with clamping lugs used for preventing the retreating of the expansion cylinder, and the upper end of the external circle of the expansion cylinder is provided with a fixing lug which is sewn with the skin of a patient to fix expansion cylinder to the patient; the top of the expansion cylinder is provided with an inner cover which can rotate around the peripheral direction of the central axis of the expansion cylinder in a reciprocating manner, and the inner cover is provided with a plurality of puncture bayonets communicated with the surgery channel; the lateral wall of the expansion cylinder is provided with an air inlet and an air outlet. The single-hole multichannel rotatable operating device has the advantages that the rotation of a surgical tool is facilitated so as to perform surgery on an affected part from different angles, and the device is simple and convenient to operate, capable of avoiding secondary injury of the patient and capable of guaranteeing fast recovery; the passing ability and sealing performance of the puncture bayonets can be increased favorably by a sealing component, and surgery operating efficiency is increased favorably.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a laparoscopic single-hole multi-channel rotatable operating device. Background technique [0002] In the case of laparotomy on the patient, the laparotomy site is large and the bleeding during the operation is large. Therefore, the recovery of the patient after the operation is slow and large scars are left, which brings great harm to the life of the patient. inconvenient. In order to overcome the disadvantages of such laparotomy, new surgical methods such as minimally invasive surgery and scarless surgery are usually used; and scarless surgery is to transfer surgical tools to the surgical site in the patient's body through the naturally existing holes in the human body. Avoid cutting the patient's body, and significantly reduce the amount of bleeding compared with open surgery, so the postoperative recovery time of the patient is shortened, and the external scars are small. ...

[0002] In the case of laparotomy on the patient, the laparotomy site is large and the bleeding during the operation is large. Therefore, the recovery of the patient after the operation is slow and large scars are left, which brings great harm to the life of the patient. inconvenient

In order to overcome the disadvantages of such laparotomy, new surgical methods such as minimally invasive surgery and scarless surgery are usually used; and scarless surgery is to deliver surgical tools to the surgical site in the patient's body through the naturally existing holes in the human body. Avoid cutting the patient's body, and significantly reduce the amount of bleeding compared with open surgery, so the postoperative recovery time of the patient is shortened, and the external scars are small. In the prior art, in the operation of the abdominal cavity through the anus, A single-hole surgical channel is formed by expanding the anus. The single-hole surgical channel is provided with multiple passages for each surgical tool to be inserted into the patient's anus and to operate on the patient's internal surgical site through the surgical channel. However, the existing single-hole surgical channel The operating device is generally fixed by an external hand or a fixing device, which makes the fixation unstable or restricts the doctor's operating space, which is not conducive to the convenience of surgical operation, and when each channel needs to be rotated, the operating device is generally rotated as a whole, resulting in a decrease in the fixing accuracy of the operating device and Difficult to operate, easy to cause secondary injury to the patient, and not conducive to the rapid recovery of the patient
