Suture line empennage hot melting forming device

Abstract

The utility model discloses a suture line empennage hot melting forming device which comprises an upper die, a lower die and a heating block which are detachable, a line passing cavity is arranged in the upper die, the line passing cavity is formed by splicing semi-groove through holes in a first die and a second die which are arranged on opposite end faces, a forming cavity is arranged in the lower die, and the shape of the forming cavity is matched with that of an empennage part. The upper die and the lower die are isolated from the heating block through the spring, so that the suture line deformation caused by overhigh temperature of the line passing cavity due to long-time contact heat transfer of the upper die and the lower die is prevented. The tail of the suture line enters the forming cavity through the line passing cavity and then is heated and melted to form a tail wing.

Description

Technical Field

[0001] The utility model relates to the technical field of hot-melt molds, in particular to a hot-melt forming device for a suture tail wing. Background Art

[0002] Existing knotless sutures are generally made by evenly distributing barbs on the thread body. They are divided into unidirectional and bidirectional types. Bidirectional barbed sutures are sutured in two directions at the center of the incision site, so there is no need to tie knots to fix them. Unidirectional barbed sutures only prevent movement in the opposite direction. Therefore, wings are usually provided at the tail of the suture. The wings can be formed by hot-melt molding at the end of the thread body. However, there are very few types of hot-melt molding devices for the tail wings of sutures on the market, and the tail wings are relatively difficult to process. Utility Model Content

[0003] The purpose of the utility model is to solve the technical problem that the types of existing suture tail hot-melt forming devices are very few and tail processing is difficult, and to provide a suture tail hot-melt forming device.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a suture line tail wing hot melt forming device, comprising a detachable upper mold, a lower mold and a heating block, a wire passing cavity is provided in the upper mold, and the wire passing cavity is composed of a first mold provided on opposite end faces and a half-groove through hole in the second mold, a molding cavity is provided in the lower mold, and the molding cavity has a shape matching the tail wing part.

[0005] Preferably, spring clips for separating and combining the first mold and the second mold are provided on both sides of the opposite end surfaces of the first mold and the second mold.

[0006] Preferably, positioning columns and springs are provided around the upper part of the heating block, positioning holes and spring holes are provided at the relative position of the lower mold, and positioning holes are provided at the relative position of the upper mold.

[0007] Preferably, two groups of quick latch holes are provided at corresponding positions of the upper die and the lower die, and the upper die and the lower die are pressed together by the quick latches.

[0008] Preferably, a heating element is provided inside the heating block and is controlled by a temperature control sensor.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] The utility model provides an upper mold, a lower mold, and a heating block, allowing the tail of the suture thread to be directly heated and melted to form a tail fin. A spring isolates the upper mold from the lower mold and the heating block, preventing prolonged contact and heat transfer between the upper and lower molds, which could cause deformation of the suture thread due to excessive temperature in the thread passage cavity. Furthermore, a certain buffering and protective effect is provided when the upper and lower molds are closed. A spring clip can join or separate the first and second molds. A quick latch ensures a tight fit between the upper and lower molds, preventing leakage of internal hot-melt material. As a result, the tail of the suture thread passes through the thread passage cavity and enters the molding cavity, where it is heated and melted to form a tail fin. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only preferred embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See Figure 1-4 The utility model provides a suture tail fin hot melt forming device, comprising a detachable upper mold 1, a lower mold 2 and a heating block 3. A wire-passing cavity is provided in the upper mold 1, and the wire-passing cavity is composed of a first mold 6 provided at opposite end faces and a half-slot through hole 4 in the second mold 7, as well as a clip 8 provided on both sides of the opposite end faces of the first mold 6 and the second mold 7 for separating and combining the first mold 6 and the second mold 7. A molding cavity 5 is provided in the lower mold 2, and the molding cavity 5 has a shape matching the tail fin portion. A heating element is provided inside the heating block 3, and the heating element can be a thermocouple, and the heating temperature is controlled by a temperature controller.

[0018] Positioning posts 9 and springs 10 are arranged around the top of the heating block 3. Positioning holes 11 and spring holes 12 are provided in the relative position of the lower mold 2, and positioning holes 11 are provided in the relative position of the upper mold 1. The upper mold 1, lower mold 2, and heating block 3 are precisely connected through the positioning posts 9 and positioning holes 11. The springs 10 isolate the upper mold 1 from the lower mold 2 and heating block 3, preventing prolonged contact and heat transfer between the upper mold 1 and the lower mold 2.

[0019] Two groups of quick latch holes 13 are provided at corresponding positions of the upper mold 1 and the lower mold 2. The quick latches can make the upper mold 1 and the lower mold 2 fit tightly together to prevent the internal hot melt material from leaking out.

[0020] The heating block 3 is powered on and heated to the molding temperature. A small section of the suture tail enters the molding cavity 5 along the thread cavity 4 and is quickly heated and melted to form the tail. After the first mold 6 and the second mold 7 are separated by the clip 8, the finished product is taken out.
