Embodiment 1

[0035] figure 1 A schematic diagram of the structure of a surgical scalpel when it is inserted and passed through the cavity of the endoscope provided in the embodiment of the present application.

[0036] figure 2 It is a schematic diagram of the structure of a surgical incision knife in the implementation of full-thickness mucosal resection provided in the embodiment of the present application.

[0037] Such as figure 1 and figure 2 As shown, the surgical knife includes: a catheter 1 , an elastic member 6 , an operating handle 7 , a first guide wire 8 and a balloon 9 . Among them: the catheter 1 is a medical plastic hose with a hollow structure with a certain hardness. It is used for surgery through the endoscope cavity pre-inserted into the living body, and reaches the target organ cavity of the operation. A side hole 2, a groove 3, a guide wire hole 4 and an air injection and water injection hole 5 are provided, and the side hole 2 and the air and water injection hol...

Embodiment 2

[0046] When performing full-thickness resection of the mucous membrane of organs with cavities in the above-mentioned minimally invasive surgery, mucosal bleeding often occurs. If timely and effective hemostasis measures are not taken, the patient will cause hemorrhagic shock due to massive blood loss, and even endanger the patient's life. Therefore, on the basis of the first embodiment of the present application, the second embodiment of the present application also provides another surgical incision knife, which can not only quickly and effectively perform full-thickness resection of the mucosa, but also compress the bleeding mucosa to stop bleeding. .

Embodiment 3

[0055] Figure 6 It is a schematic structural diagram of the third type of surgical incision knife provided in the embodiment of the present application.

[0056] Such as Figure 6 As shown, the surgical operative knife also includes: a power plug 15 and a retaining ring 16, wherein:

[0057] The power plug 15 is arranged on the operating handle 7 and connected to the first guide wire 8 for providing high-frequency current to the first guide wire 8;

[0058] The fixing ring 16 is fixed at the tail end of the catheter 1. During the operation, the operator can insert the thumb into the fixing ring 16, and insert the index finger and middle finger into the locking ring 10, so that the operator can better control the operating handle 7.

[0059] The surgical scalpel provided in the embodiment of the present application is specially designed for full-thickness mucosal resection in minimally invasive surgery. The first guide wire of high-frequency electricity crosses the surgical...

Abstract

The invention discloses an incision surgical knife which comprises a guide pipe, an elastic element, an operating handle, a first guide wire and a saccule, wherein the guide pipe is in a hollow structure, is provided with a side hole, a groove, a thread eye and a gas injection water injection hole which are sequentially arranged from the front end to the terminal end; the elastic element is embedded in the groove, and the rear end of the elastic element is fixed with the guide pipe; the operating handle is sheathed outside the guide pipe and can slide along a guide pipe shaft; the first guide wire is arranged in the guide pipe, the front end stretches out from a guide wire hole and is fixed with the front end of the elastic element, and the terminal of the first guide wire is fixed with the operating handle; and the saccule is fixed at the top of the guide pipe in a sealing way, and the side hole is arranged in the saccule. The operation incision knife provided by the embodiment of the invention is designed specially for full resection of mucous membrane in minimally invasive surgery, thus full resection on a large-area mucous membrane can be rapidly and effectively carried out in an operation, viscera except the mucous membrane can be effectively avoided, peripheral viscera can not be damaged, surgical risk is reduced, and success rate of a surgery can be improved.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to a surgical incision knife suitable for an endoscope. Background technique [0002] Minimally invasive surgery refers to a new technology of performing surgery in the human body through an endoscope, which has the advantages of less trauma, less pain and faster recovery. Minimally invasive surgery has changed the shortcoming of open surgery "big incision to solve small problems", and can achieve the effect of "small incision to solve big problems". In minimally invasive surgery, how to perform full-thickness resection of the mucous membrane of organisms with lumens has become the focus of research. [0003] Through research on the prior art, the applicant found that none of the existing mucosal incision devices is designed for the full-thickness resection of the mucous membrane of organs with cavities, and cannot quickly and effectively perform full-thickness resection of...
