Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of medical devices, and more specifically, to a clamping assembly and an ultrasonic scalpel having the same. Background Technology
[0002] Ultrasonic scalpels are widely used in surgical procedures for cutting and stopping bleeding in soft tissues, and can also be used to coagulate blood vessels.
[0003] Currently, ultrasonic scalpel heads on the market are equipped with clamping components at the tip. These clamping components are connected to the outer and inner sheaths of the ultrasonic scalpel. Driving the inner sheath drives the clamping components to open and close the jaws. During ultrasonic scalpel operation, soft tissue or blood vessels are clamped between the clamping components and the scalpel shaft. After each cut, the tissue pad of the clamping components experiences varying degrees of wear. If the wear is severe, the clamping and holding force may decrease during ultrasonic scalpel operation, or even lead to direct contact between the scalpel shaft and the clamping components, causing the scalpel shaft to break, increasing surgical risks. Therefore, even if the ultrasonic scalpel head still has good mechanical properties, it cannot be reused. Due to the wear of the tissue pad, the entire scalpel head becomes unusable, resulting in resource waste and increased medical costs.
[0004] There is currently no effective solution to the above problems. Utility Model Content

It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.
[0037] Combination Figures 1 to 8 As shown, according to a specific embodiment of this application, a clamping assembly is provided.
[0038] Specifically, the clamp assembly includes: a clamp body 1, a limiting member 3, and a tissue pad 2. The clamp body 1 is provided with a mounting structure 11, which extends through the clamp body 1 along its thickness direction; the limiting member 3 is connected to the clamp body 1, and at least a portion of the limiting member 3 is located within the mounting structure 11; the tissue pad 2 is detachably connected to the clamp body 1, and the tissue pad 2 has a working position connected to the clamp body 1 and a detachable position separated from the clamp body 1. When the tissue pad 2 is in the working position, it is located on one side of the limiting member 3; wherein, when the tissue pad 2 is in the working position, the limiting member 3 cooperates with the tissue pad 2, and the limiting member 3 limits and locks the tissue pad 2 to a locked state, and operating the limiting member 3 can switch the tissue pad 2 from the locked state to the unlocked state.
[0039] By applying the technical solution of this utility model, the tissue pad is detachably connected to the clamp body via a limiting member. The limiting member cooperates with the tissue pad to lock it onto the clamp body, and the limiting member can be operated to separate the tissue pad from the clamp body. The detachable connection between the tissue pad and the clamp body allows for the replacement of worn tissue pads, thus solving the problem of wasted blades and increased medical costs caused by tissue pad wear.
[0040] As will be understood by those skilled in the art, when the tissue pad 2 is in the working position, the tissue pad 2 is in a locked state, that is, the tissue pad 2 cooperates with the limiting member 3 to achieve the connection between the tissue pad 2 and the clamp body 1. When the tissue pad 2 is in the disassembled position, the tissue pad 2 is in an unlocked state, that is, the tissue pad 2 is separated from the limiting member 3 to achieve the separation between the tissue pad 2 and the clamp body 1.
[0041] The mounting structure 11 is a through hole provided on the clamp body 1. The through hole extends through the thickness direction of the clamp body 1, and at least part of the limiting member 3 is located in the through hole so that the limiting member 3 can be operated through the through hole, thereby realizing the installation and removal of the tissue pad 2.
[0042] Furthermore, the limiting member 3 includes an mounting section 31 and a limiting section 32. The mounting section 31 is connected to the clamp body 1, and the limiting section 32 is movably disposed along the depth direction of the mounting structure 11, so that the limiting section 32 has a first state of abutting against the tissue pad 2 to restrict the movement of the tissue pad 2 relative to the clamp body 1, and a second state of being separated from the tissue pad 2. The mounting structure 11 is a through hole, through which the limiting section 32 is operated to move the limiting section 32 closer to and away from the tissue pad 2, thereby realizing the abutment and separation of the limiting section 32 from the tissue pad 2, which is simple to operate.
[0043] Specifically, the clamp body 1 has an inwardly recessed mounting groove 14 near the tissue pad 2, and the mounting section 31 is connected within the mounting groove 14. The depth of the mounting groove 14 is equal to or greater than the thickness of the mounting section 31, preventing the mounting section 31 from protruding from the connecting surface of the clamp body 1, making the connecting surface of the clamp body 1 flat, so that the tissue pad 2 and the clamp body 1 fit tightly together, avoiding gaps between the tissue pad 2 and the clamp body 1, and making the connection between the tissue pad 2 and the clamp body 1 more secure.
[0044] like Figure 3 , Figure 4 As shown, the mounting groove 14 is located close to the mounting structure 11. The mounting section 31 has three welding holes. The mounting groove 14 has three connecting posts that correspond one-to-one with the welding holes. The welding holes are inserted into the connecting posts, and the mounting section 31 is welded to the connecting posts by laser welding.
[0045] In one exemplary embodiment, the limiting member 3 is a leaf spring. The mounting section 31 and the limiting section 32 are arranged at an angle. Under the action of an external force, the limiting section 32 twists relative to the mounting section 31 to move away from the tissue pad 2. Under the action of an elastic force, the limiting section 32 moves closer to the tissue pad 2 to abut against the tissue pad 2. The leaf spring achieves flexible limiting of the tissue pad 2 through its own elastic force, that is, it can be twisted away from the tissue pad 2 by an external force, and it can also be pressed against the tissue pad 2 by its own elastic force. The leaf spring is made of metal plate, has good elasticity and bending performance, can withstand large deformation and has high elastic recovery force, can withstand long-term use without fatigue damage, saves costs, and the leaf spring has a simple structure, small size and saves space.
[0046] It should be noted that when the limiting segment 32 is not subjected to external force, the limiting segment 32 is in the initial state (first state), and the limiting segment 32 abuts against the tissue pad 2 to restrict the movement of the tissue pad 2 relative to the clamp body 1; under external force, the limiting segment 32 twists relative to the mounting segment 31 and moves away from the tissue pad 2 to release the restriction on the tissue pad 2, that is, the tissue pad 2 can move relative to the clamp body 1; after the external force disappears, the limiting segment 32 returns to the initial state (first state) under the action of its own elastic force, and then abuts against the tissue pad 2.
[0047] Furthermore, a limiting groove 22 is provided on the side of the tissue pad 2 near the clamp body 1. When the limiting segment 32 is in the first state, a portion of the limiting segment 32 extends into the limiting groove 22, and the limiting segment 32 abuts against the inner wall of the limiting groove 22. With the limiting segment 32 extending into the limiting groove 22 and abutting against its inner wall, the tissue pad 2, under the action of horizontal force, cannot cause the limiting segment 32 to move vertically upwards; that is, the limiting segment 32 cannot disengage from the limiting groove 22, making the limiting of the tissue pad 2 by the limiting segment 32 more reliable. In addition, the design of the limiting segment 32 tightly abutting against the inner wall of the limiting groove 22 ensures that the tissue pad 2 remains stable during use and accurately positions its connection with the clamp body 1, preventing the tissue pad 2 from moving or swinging during clamp operation. Through the cooperation of the limiting segment 32 and the limiting groove 22, the position and movement of the tissue pad 2 can be effectively controlled, improving stability and safety.
[0048] Specifically, the tissue pad 2 is slidably connected to the clamp body 1 along its length, and the limiting segment 32 abuts against the tissue pad 2 along its length. The slidable connection of the tissue pad 2 to the clamp body 1 restricts its movement along this direction. The limiting segment 32 only restricts the movement of the tissue pad 2 along the length of the clamp body 1, simplifying its structure. Furthermore, the sliding connection between the tissue pad 2 and the clamp body 1 provides a positioning function, facilitating the positioning connection between them.
[0049] like Figure 1 , Figure 3 , Figure 4 As shown, the clamp body 1 is provided with a second sliding groove 13, which extends along the length of the clamp body 1; the tissue pad 2 is provided with a second sliding rail 21, which is slidably connected to the second sliding groove 13 via the second sliding rail 21, wherein the second sliding rail 21 is an I-shaped structure.
[0050] Furthermore, the limiting segment 32 has a V-shaped structure and includes a first spring piece 321 and a second spring piece 322. The mounting segment 31, the first spring piece 321, and the second spring piece 322 are connected sequentially. The first spring piece 321 is set at a first angle to the mounting segment 31, and the first spring piece 321 is set at a second angle to the second spring piece 322. When the limiting segment 32 is in the first state, the outer wall of the second spring piece 322 is in contact with the inner wall of the limiting groove 22. The mounting segment 31 has a sheet-like structure. By designing the limiting segment 32 as a V-shaped structure, when the limiting segment 32 is in the first state, both the first spring piece 321 and the second spring piece 322 are located within the limiting groove 22. When the limiting segment 32 is subjected to a horizontal force, the first spring piece 321 and the second spring piece 322 deform only within the limiting groove 22 and will not detach from the limiting groove 22.
[0051] like Figure 6 As shown, when the limiting segment 32 is in the first state, the mounting segment 31 is tightly attached to the top surface of the tissue pad 2 and a part of the mounting segment 31 is located above the limiting groove 22. The outer wall of the second spring piece 322 is attached to the inner wall of the limiting groove 22, but the height of the second spring piece 322 is higher than the depth of the limiting groove 22. The second spring piece 322 can be moved through the upper opening of the mounting structure 11, and the first included angle and the second included angle change accordingly, so that the limiting segment 32 and the limiting groove 22 of the tissue pad 2 are separated. At this time, the limiting segment 32 has a second state of being separated from the tissue pad 2.
[0052] In another exemplary embodiment, the tissue pad 2 includes a first connecting pad 23 and a second connecting pad 24. The first connecting pad 23 is detachably connected to the clamp body 1; the second connecting pad 24 is detachably connected to the clamp body 1, and the second connecting pad 24 abuts against the first connecting pad 23 along the length of the clamp body 1; wherein the hardness of the first connecting pad 23 and the hardness of the second connecting pad 24 are different. The material hardness of the first connecting pad 23 and the second connecting pad 24 can be adjusted according to their shapes and lengths, thereby improving the overall hardness of the tissue pad 2 and enhancing its wear resistance. Furthermore, designing the tissue pad 2 as having a first connecting pad 23 and a second connecting pad 24 allows for the replacement of the first connecting pad 23 and the second connecting pad 24 as needed, saving costs.
[0053] like Figure 8 As shown, the second connecting pad 24 is installed at the distal end of the clamp body 1, and the first connecting pad 23 is installed at the proximal end of the clamp body 1 (near the handle of the ultrasonic scalpel). The length of the first connecting pad 23 is greater than the length of the second connecting pad 24. The working surface of the first connecting pad 23 has a wavy pattern. The purpose of these patterns is to increase friction, provide better anti-slip performance, prevent the tissue pad 2 from sliding or shifting during use, and reduce wear on the tissue pad 2. The first connecting pad 23 is made of PTFE material with high hardness.
[0054] Furthermore, the clamp body 1 is provided with a first sliding groove 12 with one open end, and the first connecting pad 23 is provided with a first sliding rail 25. The first connecting pad 23 is slidably connected to the first sliding groove 12 through the first sliding rail 25. One end of the first connecting pad 23 abuts against the groove wall of the first sliding groove 12, and the other end of the first connecting pad 23 abuts against the second connecting pad 24. The second connecting pad 24 is detachably connected to the clamp body 1 through a limiting member 3. The sliding connection between the first connecting pad 23 and the first sliding groove 12 through the first sliding rail 25 allows the first connecting pad 23 to move along a predetermined path, achieving high-precision positioning. The use of a sliding groove and sliding rail connection can also reduce friction during movement and improve movement efficiency.
[0055] like Figure 3 , Figure 7 As shown, the clamp body 1 is also provided with a relief groove 15 and a second sliding groove 13. The first connecting pad 23 can be inserted through the relief groove 15 and then slide backward along the length direction of the first sliding groove 12 to abut against the groove wall of the first sliding groove 12. The second connecting pad 24 is provided with a second sliding rail 21. The second connecting pad 24 is slidably connected to the second sliding groove 13 through the second sliding rail 21. The dimensions of the second sliding rail 21 and the second sliding groove 13 are perfectly matched. The second connecting pad 24 is inserted through the opening at the front end of the clamp body 1. The length of the second sliding rail 21 protrudes outward from the second connecting pad 24, while the length of the first sliding rail 25 is shorter than the length of the first connecting pad 23. Both the first sliding rail 25 and the second sliding rail 21 are I-shaped structures. Therefore, the second connecting pad 24 and the first connecting pad 23 can abut tightly without any gap between them, ensuring the tightness and firmness of the connection.
[0056] According to another specific embodiment of this application, an ultrasonic scalpel is provided, which includes a clamping assembly, the clamping assembly being the clamping assembly in the above embodiment.
[0057] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0058] 1. The tissue pad is detachably connected to the clamp body via a limiting member. The limiting member cooperates with the tissue pad to lock the tissue pad onto the clamp body, and the limiting member can be operated to separate the tissue pad from the clamp body. By replacing the worn tissue pad, the problem of wasted blades and increased medical costs caused by tissue pad wear can be solved.
[0059] 2. The tissue pad consists of two parts: a first connecting pad 23 and a second connecting pad 24. These two parts are made of different materials and are detachably connected to the clamp body. The first connecting pad 23 and the second connecting pad 24 can be replaced separately according to wear conditions, saving costs. The material hardness of the first connecting pad 23 and the second connecting pad 24 can be adjusted according to their shape and length, thereby increasing the overall hardness of the tissue pad 2 and improving its wear resistance.
