Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a clip applicator head with a fixed elastic piece. Background Art

[0002] In laparoscopic surgery, a clip applicator is a common surgical instrument; most of the currently used polymer vascular clips and medical metal clips are used in conjunction with a clip applicator to clamp blood vessels and tissues by picking up the polymer vascular clips or medical metal clips with the clip applicator.

[0003] During the use of laparoscopic surgery, the clip applicator takes out a degradable magnesium metal closure clip from the base and enters the abdominal cavity through a trocar. After clamping some blood vessels or tissues, some degradable magnesium metal closure clips may hook with the clip applicator head, resulting in the clip applicator being unable to be smoothly removed from the laparoscope, which is likely to reduce the efficiency of clinical surgery. Summary of the Invention

[0004] In order to improve the problems existing in the above technology, this application provides a clip applicator head with a fixed elastic piece.

[0005] This application provides a clip applicator head with a fixed elastic piece, adopting the following technical solutions:

[0006] A clip applicator head with a fixed elastic piece includes: a head body and a fixed elastic piece for fixing a degradable magnesium metal closure clip. The fixed elastic piece is arranged on the head body, and a clamping assembly for fixing the degradable magnesium metal closure clip is arranged on the fixed elastic piece.

[0007] By adopting the above technical solutions, when the head body needs to pick up a degradable magnesium metal closure clip, the fixed elastic piece can be moved towards the end far away from the head body; during this process, the clamping assembly can clamp and fix the degradable magnesium metal closure clip; and after clamping tissues or blood vessels, the fixed elastic piece can be reset by the clamping force applied by the clip applicator, so as to effectively prevent the hooking phenomenon between the head body and the degradable magnesium metal closure clip.

[0008] Optionally, the clamping assembly is composed of two symmetrically arranged clamping pieces, and the clamping pieces are fixed on the fixed elastic piece.

[0009] By adopting the above technical solutions, by using the clamping elasticity of the two clamping pieces approaching each other, the degradable magnesium metal closure clip can be tightly clamped and fixed, so that not only the degradable magnesium metal closure clip has a stable fixing degree to achieve the effect of preventing the degradable magnesium metal closure clip from falling off, but also the hooking problem of the degradable magnesium metal closure clip can be solved.

[0010] Optionally, an orbital groove is formed in the fixed elastic piece, and the fixed elastic piece is slidably mounted on the jaw body through the orbital groove.

[0011] By adopting the above technical solution, the fixed elastic piece can move stably on the jaw body by the restriction of the orbital groove, so that it is not easy to move randomly.

[0012] Optionally, the clamping piece includes: Piece One, and Piece One is fixed on the fixed elastic piece.

[0013] By adopting the above technical solution, Piece One is convenient for releasing the biodegradable magnesium metal clip, so as to release the clamping of the biodegradable magnesium metal clip.

[0014] Optionally, the clamping piece further includes: Piece Two, and Piece Two is fixed on the end of Piece One away from the fixed elastic piece.

[0015] By adopting the above technical solution, Piece Two can increase the contact area between the clamping piece and the biodegradable magnesium metal clip, so as to clamp and fix the biodegradable magnesium metal clip more stably.

[0016] Optionally, the clamping piece further includes: Piece Three, and Piece Three is fixed on the end of Piece Two away from Piece One.

[0017] By adopting the above technical solution, Piece Three is convenient for placing the biodegradable magnesium metal clip between Piece Two for clamping.

[0018] Optionally, the material of the fixed elastic piece is a flexible metal material.

[0019] By adopting the above technical solution, it is not only convenient for the fixed elastic piece to deform, but also has a long service life.

[0020] In summary, the present application includes at least one of the following beneficial effects:

[0021] 1. When the jaw body needs to take the biodegradable magnesium metal clip, the fixed elastic piece can be moved towards the end away from the jaw body; during this process, the clamping assembly can clamp and fix the biodegradable magnesium metal clip; and after clamping the tissue or blood vessel, through the clamping force applied by the clip applicator, the fixed elastic piece can be reset, so as to effectively prevent the hooking phenomenon between the jaw body and the biodegradable magnesium metal clip.

[0022] 2. By the restriction of the orbital groove, the fixed elastic piece can move stably on the jaw body, so that it is not easy to move randomly.

[0023] 3. It is not only convenient for the fixed elastic piece to deform, but also has a long service life. Description of the Drawings

[0025] Figure 2 is Figure 1 a schematic partial enlarged view of part A in

[0026] In the figure: 1, the main body of the clamp head; 2, the fixed elastic piece; 21, the track groove; 3, the degradable magnesium metal closing clip; 4, the clamping assembly; 41, the clamping piece; 411, piece one; 412, piece two; 413, piece three. Specific embodiments

[0027] The present application provides a clamp head of a clip applicator with a fixed elastic piece.

[0028] Referring to Figure 1 , a clamp head of a clip applicator with a fixed elastic piece includes: the main body 1 of the clamp head and the fixed elastic piece 2 for fixing the degradable magnesium metal closing clip 3. In this embodiment, a single clip applicator includes two main bodies 1 of the clamp head, and the fixed elastic piece 2 is in the shape of a house; a track groove 21 is formed on one side of the fixed elastic piece 2 facing the main body 1 of the clamp head, and the fixed elastic piece 2 is slidably mounted on the main body 1 of the clamp head through the track groove 21, so that the fixed elastic piece 2 can stably move on the main body 1 of the clamp head, and thus is not likely to move randomly.

[0029] Referring to Figure 1 , further, in this embodiment, the material of the fixed elastic piece 2 can be a highly elastic and flexible metal material that can reach the medical grade, which not only facilitates the deformation of the fixed elastic piece 2, but also has a long service life.

[0030] Referring to Figure 2 , a clamping assembly 4 is fixedly arranged on the fixed elastic piece 2. When the main body 1 of the clamp head needs to pick up the degradable magnesium metal closing clip 3, the fixed elastic piece 2 can be moved towards the end far from the main body 1 of the clamp head; during this process, the clamping assembly 4 can clamp and fix the degradable magnesium metal closing clip 3; and after clamping the tissue or blood vessel, through the clamping force applied by the clip applicator, the fixed elastic piece 2 can be reset, so as to effectively prevent the hooking phenomenon between the main body 1 of the clamp head and the degradable magnesium metal closing clip 3.

[0031] Referring to Figure 2 , in this embodiment, a single clamping assembly 4 is composed of two symmetrically arranged clamping pieces 41, and the clamping pieces 41 are integrally formed on the fixed elastic piece 2. By using the clamping elastic force of the two clamping pieces 41 approaching each other, the degradable magnesium metal closing clip 3 can be tightly clamped and fixed, so that not only the degradable magnesium metal closing clip 3 has a stable fixing degree to achieve the effect of preventing the degradable magnesium metal closing clip 3 from falling off, but also the hooking problem of the degradable magnesium metal closing clip 3 can be solved.

[0032] Referring toFigure 2 , further, the clamping piece 41 is composed of a first piece 411, a second piece 412 and a third piece 413. One end of the first piece 411 is integrally formed on the fixed elastic piece 2, and the other end is integrally formed with the second piece 412. And the first piece 411 is inclined, that is, the first piece 411 and the second piece 412 are arranged at an obtuse angle, so that the clamp head body 1 can push the first piece 411, so that the two second pieces 412 in a single clamping assembly 4 move away from each other, thus facilitating the placement of the degradable magnesium metal clip 3; and the second piece 412 can increase the contact area between the clamping piece 41 and the degradable magnesium metal clip 3, so as to clamp and fix the degradable magnesium metal clip 3 more stably.

[0033] See Figure 2 , the third piece 413 is integrally formed on the end of the second piece 412 away from the first piece 411, and the third piece 413 is inclined, that is, the second piece 412 and the third piece 413 are also arranged at an obtuse angle. The third piece 413 can more conveniently place the degradable magnesium metal clip 3 between the two second pieces 412.

[0034] The working principle of a clip-applying forceps head with a fixed elastic piece in the present application during use is specifically as follows: When the clamp head body 1 needs to pick up the degradable magnesium metal clip 3, the fixed elastic piece 2 can be moved towards the end away from the clamp head body 1; during this process, the clamping piece 41 can clamp and fix the degradable magnesium metal clip 3; and after clamping the tissue or blood vessel, through the clamping force applied by the clip-applying forceps, the fixed elastic piece 2 can be reset, so as to effectively prevent the hooking phenomenon between the clamp head body 1 and the degradable magnesium metal clip 3.

[0035] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
