Embodiment 1

[0038] Such as figure 1 As shown, an umbrella-shaped negative pressure suction forceps for soft tissue specimens includes a forceps body 2, a basket 1, and a handle portion arranged at the tail end of the forceps body 2; At the same time, it improves the efficiency of intraoperative specimen removal and shortens the operation time, thereby reducing the risk of anesthesia and surgery for patients.

[0039] The handle portion includes a fixed handle 31 and a movable handle 32, the fixed handle 31 and the movable handle 32 are connected by hinge pins, and the fixed handle 31 is fixed on the pliers body 2;

[0040] Such as figure 2 As shown, the basket 1 includes four flat elastic metal strips 11, and each flat elastic metal strip 11 is provided with barbs 12 at the front end of the inner surface; the barbs 12 of different flat elastic metal strips 11 should be different from each other. Interfering;

[0041] The caliper body 2 is axially provided with four guide passages even...

Embodiment 2

[0047] The difference from Embodiment 1 is that the angle between the groove wall and the groove bottom of the guide groove is an acute angle, so that the opening cross-sectional size of the guide groove gradually decreases from the groove bottom to the outside, as Figure 5 As shown, the flat elastic metal strip 11 can be effectively prevented from falling from the guide channel 21 .

Embodiment 3

[0049] The difference from Embodiment 1 is that the guide channel 21 and the negative pressure suction channel 22 are directly processed on the pliers body 2, such as Figure 6 shown.

[0050] In other embodiments, for the sake of compact structure, the guide channel 21 and the negative pressure suction channel 22 are located on the same circumference and evenly distributed.

Abstract

The invention provides umbrella-shaped negative pressure suction forceps for a soft tissue specimen, and solves the problems that an existing method for taking out bladder tumor tissues is low in efficiency and the specimen is easy to remain, or the operation risk is increased due to long operation time. The suction forceps comprise a forceps body, a mesh basket and a handle portion arranged at the tail end of the forceps body, wherein the handle portion comprises a fixed handle and a movable handle; the mesh basket is composed of at least three flat elastic metal bands, and a plurality of barbs are arranged at the front end of the inner surface of each flat elastic metal band in the mesh basket; at least three guide channels which are uniformly distributed in the circumferential directionare formed in the forceps body in the axial direction, the number of the guide channels is equal to that of the flat elastic metal bands, and the positions of the guide channels correspond to those of the flat elastic metal bands one to one; the rear end of each flat elastic metal band penetrates through the corresponding guide channel on the forceps body and then is connected with the movable handle; and the forceps body is provided with at least one negative pressure suction channel in the axial direction, one end of each negative pressure suction channel is open on the end surface of the front end of the forceps body, and the other end of each negative pressure suction channel is open at the rear end or the rear portion of the forceps body.

Description

technical field [0001] The invention relates to a medical operation instrument, in particular to an umbrella-shaped negative pressure suction forceps for soft tissue specimens. Background technique [0002] Bladder cancer is one of the most common clinical tumors in urology, and it is also a disease that directly threatens the survival of patients. Transurethral resection of bladder tumor (TUR-BT) is not only an important diagnostic method for non-muscle invasive bladder cancer, but also the main treatment. In recent years, with the rapid development of minimally invasive surgery, various types of transurethral bladder tumor resection (electrical resection, plasma, laser, etc.) have developed rapidly. Surgery requires that the resected bladder tumor tissue (specimen) must be completely removed, especially in recent years. The tumor is resected en bloc and the specimen is taken out in one go. [0003] At present, there are two clinical methods for removing the above-mention...
