Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a surgical clamp ligation forceps. Background Technology

[0002] Chinese patent CN119655820A discloses a surgical clamp ligation forceps, including a fixed handle, a grip, a push-pull rod, a clamping rod, and a forceps head. The surgical clamps are inserted into the clamping rod. The forceps also include an outer sleeve fitted over the clamping rod and push-clamp springs slidably mounted on the clamping rod. One end of the surgical clamp has a transverse column. The push-clamp springs have several push-out springs extending obliquely towards the front end of the inner wall of the clamping rod. The front end of each push-out spring has a semi-circular push-out limiting opening that presses and limits the transverse column. The clamping rod has several anti-backward springs extending obliquely towards the front end of the push-clamp springs. The front end of each anti-backward spring has a semi-circular anti-backward limiting opening that presses and limits the transverse column. This invention can accommodate multiple surgical clamps and precisely and stably extend them, preventing them from falling out, effectively improving surgical safety. Furthermore, the trigger design of the handle allows the user to control the extension process, facilitating the surgical procedure.

[0003] In the aforementioned patents, the bending portion at the front end of the outer sleeve mostly uses right-angle turns. However, due to the thickness of the material, it is impossible to bend it into a perfect right angle when making a direct bend. In fact, a certain rounded corner will appear at the bend. The appearance of the rounded corner will reduce the actual space inside the outer sleeve, making it easy for the outer sleeve to interfere with other internal parts. Therefore, in view of the above situation, there is an urgent need to develop a surgical clip ligation forceps that eliminates the effect of the rounded corner caused by the direct edge bend through the setting of rolled edge, which can increase the actual space inside, obtain a certain elastic deformation capability, and prevent interference with internal parts, so as to overcome the shortcomings of the current practical application and meet the current needs. Utility Model Content

[0004] The purpose of this invention is to provide a surgical clamp ligation forceps to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A surgical clamp ligation forceps includes a handle, a metal outer sleeve, and a clamping rod. The handle is connected to the clamping rod. A metal outer sleeve is installed on the outside of the clamping rod. A geometric sleeve is provided at the front end of the metal outer sleeve, which is fitted over the outside of the forceps head. The left and right corners of the metal outer sleeve are respectively provided with rolled edges that protrude outwards.

[0007] Preferably, the metal outer sleeve is made of 304 stainless steel.

[0008] The beneficial effects of this utility model are as follows: This surgical clamp ligation forceps, through the design of the rolled edge, can eliminate the effect of rounded corners caused by right-angled edge transitions, thereby increasing the actual internal space of the geometric sleeve and preventing interference between the geometric sleeve and its internal components. Furthermore, the outward protrusion of the rolled edge gives the geometric sleeve a certain degree of elastic deformation capability, allowing it to elastically deform and make way for other components when the inner wall of the geometric sleeve is subjected to pressure or friction. In summary, this utility model, through the design of the rolled edge, eliminates the effect of rounded corners caused by right-angled edge transitions, increases the actual internal space, and provides a certain degree of elastic deformation capability, preventing interference with internal components.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Specific implementation examples are given below.

[0017] See Figures 1-4In this embodiment of the present invention, a surgical clamp ligation forceps includes a handle 1, a metal outer sleeve 2, and a clamping rod 3. The handle 1 is connected to the clamping rod 3. A clamping head 4 is installed at the front end of the clamping rod 3. The metal outer sleeve 2 is installed on the outside of the clamping rod 3. A geometric sleeve 21 is provided at the front end of the metal outer sleeve 2. The geometric sleeve 21 is fitted over the outside of the clamping head 4. The left and right corners of the metal outer sleeve 2 are respectively provided with rolled edges 211. The rolled edges 211 protrude outward. The outward protrusion of the rolled edges 211 can increase the actual space inside the geometric sleeve 21, preventing the inside of the geometric sleeve 21 from interfering with the clamping head 4. In addition, because the rolled edges 211 protrude outward, the geometric sleeve 21 itself has a certain elastic deformation capability (similar to a spring). If the inner wall of the geometric sleeve 21 is squeezed or rubbed against other parts, it can elastically deform to make way.

[0018] The metal outer tube 2 is made of 304 stainless steel.

[0019] Working principle: This surgical clamp ligation forceps, through the setting of the rolled edge 211, can eliminate the effect of the rounded corner caused by the right angle edge turning, which can increase the actual space inside the geometric sleeve 21 and prevent the geometric sleeve 21 from interfering with the internal parts. In addition, because the rolled edge 211 protrudes outward, the geometric sleeve 21 itself has a certain elastic deformation capability (similar to a spring). If the inner wall of the geometric sleeve 21 is squeezed or rubbed with other parts, it can elastically deform to make way.

[0020] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
