Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a clamp for processing biomembranes for uterine cavity repair. Background Technology

[0002] Endometrial problems are common gynecological conditions, including intrauterine adhesions and endometriosis. The most common clinical treatment is hysteroscopic surgery. Generally, membranous adhesions or fibromyalgia can be separated or surgically removed hysteroscopically, often combined with hormone therapy. However, the recurrence rate after surgery is approximately 3.1% to 23.5%, with severe intrauterine adhesions showing a recurrence rate as high as 50%. Nomaier Medical Technology Co., Ltd. has independently developed and produces an endometrial repair membrane that promotes the growth of epithelial cells in the functional layer of the endometrium, aiming to safely, efficiently, and simply treat gynecological diseases such as endometrial problems. The method of use is as follows: after hysteroscopic surgery, the ERM membrane spreads to cover the entire uterine cavity, forming a physical barrier within the cavity to prevent the recurrence of adhesions. It also promotes the repair of the functional and basal layers of the endometrium, accelerating the regeneration of damaged endometrium to achieve the therapeutic goal. To ensure the smooth unfolding of the ERM membrane after it is delivered into the uterine cavity, the ERM membrane needs to be processed into a bag. Currently, the existing processing clamps cannot clamp the ERM membrane into a bag structure of the corresponding size. Moreover, most of the clamps of the existing processing clamps have fixed clamp heads, which cannot process ERM membranes for uterine cavities of different sizes. Additional processing clamps need to be designed for processing, which has significant limitations in use. Summary of the Invention

[0003] The purpose of this invention is to address the problem that existing processing clamps are difficult to process ERM membranes into specific shapes, which prevents membrane-like uterine repair products from functioning in the uterine cavity environment. Therefore, this invention proposes a uterine cavity repair biomembrane processing clamp.

[0004] The technical solution of the present invention is: a clamp for processing biomembranes for uterine cavity repair, comprising two clamp arms that are hinged to each other; the tail end of each clamp arm is provided with a gripping part, and the front end is provided with a clamping part; the clamping part is in the shape of a trapezoidal frame.

[0005] One of the clamping parts is open.

[0006] Another clamping part is in the shape of a closed trapezoid, and has a support arm in its middle; the support arm is an extension of the clamp arm and is fixedly connected to the middle of the upper and lower bottom edges on the trapezoidal frame.

[0007] The area enclosed by the clamping part is adjustable. The clamping part includes a lower clamping arm, an upper clamping arm, and two retractable side clamping arms; the lower clamping arm is fixedly connected to the clamping arm; connecting sleeves are hinged to both ends of the side clamping arms; the connecting sleeves at both ends of the side clamping arms are slidably and lockably connected to the upper clamping arm and the lower clamping arm, respectively.

[0008] The upper clamping arm and the lower clamping arm are fixed with a support member consisting of two guide rods that can be locked and slidably connected.

[0009] The gripping part is a gripping hole.

[0010] The two clamp arms have interlocking locking teeth on their opposite ends.

[0011] The side clamping arm is divided into two sections; the two sections are slidably connected by a sleeve.

[0012] Both ends of the lower and upper clamping arms are provided with rack portions along the length direction on both sides; the inside of the connecting sleeve is provided with elastic protrusions on both sides that can lock with the rack portions of the upper and lower clamping arms.

[0013] The support members in the middle of the upper clamping arm and the middle of the lower clamping arm are locked with screws.

[0014] The present invention has the following beneficial effects by adopting the above technical solution: (1) The clamping part of the uterine cavity repair biomembrane processing clamp of the present invention is set in a trapezoidal shape, and the size of the area enclosed by the clamping part is adjustable. The size of the clamping part can be adjusted according to the needs, so as to adapt to the processing of biomembranes of different sizes, and thus can adapt to patients with different sizes of uterine cavity for surgery, with strong applicability.

[0015] (2) The clamping part of the present invention is composed of a lower clamping arm, an upper clamping arm and two side clamping arms. The connecting sleeves at both ends of the side clamping arms are slidably and lockably connected to the upper clamping arm and the lower clamping arm respectively. The position of the side clamping arm can be adjusted by adjusting the position of the connecting sleeve on the upper clamping arm and the lower clamping arm, thereby adjusting the size of the clamping part. The adjustment is very convenient.

[0016] (3) The side clamping arm of the present invention is telescopic, and the area of ​​the clamping part can be adjusted while keeping the distance between the upper clamping arm and the clamping arm unchanged.

[0017] (4) The middle part of the upper clamping arm and the middle part of the lower clamping arm of the present invention are fixed with a support member consisting of two guide rods that can be locked and slidably connected, so as to ensure that the entire clamping part remains in a relatively stable state when the area of ​​the clamping part is adjusted, so as to facilitate stable clamping.

[0018] (5) The gripping part of the present invention adopts a gripping hole, which not only saves materials, but also provides high gripping stability.

[0019] (6) The clamp arms of the present invention have interlocking locking teeth on the opposite surfaces of the tail ends, which can keep the processing clamps in a clamping state at all times, without the need for continuous manual force application, thus reducing the burden on medical staff.

[0020] (7) The side clamping arm of the present invention is divided into two sections; the two sections are slidably connected by a sleeve rod, which not only makes the structure simple, but also makes the movement between the two side clamping arms smoother.

[0021] (8) The connecting sleeve of the present invention is locked with the rack part by the elastic protrusion, and the position of the connecting sleeve can be adjusted at any time, making the adjustment more convenient.

[0022] (9) The support members in the middle of the upper clamping arm and the middle of the lower clamping arm of the present invention are locked with screws, which makes locking more convenient. Attached Figure Description
