Description

Technical Field

[0001] The utility model relates to the technical field of medical tools, in particular to a reel component and an abdominal puncture device using the component. Background Art

[0002] Laparoscopic surgery has gradually replaced traditional surgery due to its advantages such as less trauma, less physiological interference to patients, good cosmetic effect, less pain, and faster recovery. It has been widely used in general surgery, gynecology, and cardiothoracic surgery. Laparoscopic surgery requires opening a hole in the patient's abdomen and performing the operation under laparoscopic observation. Fascia suture is required after the operation. Fascia suture is difficult to operate due to the small incision and deep inner wall. The current solutions include manual suturing and fascia suturer suturing. Manual suturing is suitable for thin patients. For obese patients, the abdominal wall tissue is thick and cannot meet the requirements of accurate and effective suturing of the puncture incision, leading to a series of complications such as bleeding, infection, puncture hernia and injury. Fascia suturer suturing can suture the fascia of obese patients, but the puncture device must be pulled out first, and then the fascia suturer must be operated. The operation is complicated and the operation time is long, which increases the risk of infection for patients.

[0003] For the above reasons, currently, the abdominal puncture device has gradually added a push-pin suturing mechanism, for example, the Chinese invention patent with the patent application number CN202111344054.6 discloses a push-pin suturing structure for a laparoscopic puncture suturing device, and the Chinese invention patent with the patent application number CN201480057286.5 discloses a trocar and wound closure device. Both of them are based on the original abdominal puncture device, and the wound suturing mechanism is added, so that the patient's wound can be quickly sutured after the operation is completed.

[0004] For example, the above-mentioned patents and other similar abdominal puncture devices with wound suturing function in the prior art all require sutures and rivet sutures to be preset in the abdominal puncture device, and the whole is assembled in the abdominal puncture device. Since the sutures need to be in a straight state when in use to avoid being entangled or interfering with other components during use, the sutures are tensioned by an internal tensioning mechanism when stored in the abdominal puncture device.

[0005] For example, in the above-mentioned patent: Trocar and wound closure device, it is recorded in the specification: "In some embodiments, the reel includes a mechanism to provide automatic retraction of multiple sutures, such as during the setting of anchoring. Optionally, the mechanism includes the use of one or more clocksprings, operably connected to the reel. A potential advantage of storing multiple sutures on a reel may include reducing the risk of suture entanglement and / or curling, reducing the risk of multiple sutures interfering with the passage of the tool through the cannula, reducing the risk of multiple sutures interfering with the advancement of the trocar through the cannula, and / or other advantages."

[0006] Based on the above technology, at present, when fixing on the reel, adhesive is basically used for fixing, one end of the ring is connected to the rivet, and the other end is bonded to the reel, and then the torsion spring in the reel is used to wind the excess onto the reel to tighten it. In the process of processing by adhesive fixation, it is necessary to wait for the adhesive to solidify after each adhesive installation before continuing the subsequent processing, which prolongs the processing time of a single process. Moreover, when releasing, a certain amount of force is required to tear it off the reel and separate it from the reel, so as to facilitate the subsequent operation of suturing the wound. The amount of adhesive and the bonding length will affect the bonding strength. During processing, there will be some deviations in the amount of adhesive and the bonding length, resulting in different forces required for the finished puncture device when it is released. If the amount of adhesive is too little, it cannot produce enough bonding force, and it may also cause the suture to fall off the reel during the assembly process. Utility Model Content

[0007] The utility model aims to provide a reel assembly and an abdominal puncture device using the assembly, so as to solve the problem in the prior art that the reel is fixed by bonding, and after processing is completed, it is necessary to wait for the adhesive to solidify before continuing the subsequent processing, which prolongs the processing time of a single process.

[0008] In order to solve the above technical problems, the first technical solution adopted by the utility model is:

[0009] A reel assembly comprises a disk-shaped reel body, a winding groove is recessed around the side of the reel body, a winding post is protruded from the bottom of the winding groove, an elastic groove is recessed on one side of the reel body, a first rotating shaft is protruded from the middle of the bottom of the elastic groove, a fixing post is protruded from the bottom of the elastic groove, a torsion spring is installed in the elastic groove, one end of the torsion spring is connected to the winding post, and the other end extends out of the outside of the elastic groove.

[0010] A further technical solution is that the groove wall of the winding groove is recessed at the position of the winding post in a direction away from the winding post to form an installation opening.

[0011] A further technical solution is that a second rotating shaft is provided on the middle protrusion of the reel body on the side away from the elastic groove, and the axis of the first rotating shaft and the second rotating shaft are the same.

[0012] A further technical solution is that a groove wall surrounding the elastic groove is provided with a plurality of ribs protruding toward the middle of the elastic groove.

[0013] A further technical solution is that one end of the winding post away from the bottom of the winding groove protrudes from the notch of the winding groove, and the depth of the winding groove at the position of the winding post is lower than the depth of other positions of the winding groove.

[0014] The second technical solution adopted by the utility model is:

[0015] A abdominal puncture device comprises a sleeve, wherein a connecting tube is connected to the upper end of the sleeve, suture staples are arranged on both sides of the inner wall of the lower end of the sleeve, a puncture cone assembly is installed in the connecting tube and the sleeve, and a staple pushing mechanism for pushing the suture staple out of the sleeve is arranged on the puncture cone assembly, a shell is installed on the outer side of the connecting tube, an installation cavity is formed between the shell and the sleeve, a reel body as in the first technical solution is rotatably installed on both sides of the opposite sides of the connecting tube in the installation cavity, one end of the torsion spring extending out of the elastic groove is connected to the outer wall of the connecting tube, a wire is wound in the winding groove, and the free end of the wire passes through the shell and is connected to the suture staple.

[0018] Compared with the prior art, the utility model has at least one of the following beneficial effects: 1. By setting a winding groove, the suture can be stored in the winding groove when it is wound on the reel body and will not slip off the reel body; 2. By setting a winding post, after passing through the suture nail rivet, it is made into a ring shape by bonding or knotting, so that it only needs to be hung on the winding post before winding on the reel body, and there is no need to wait for the time to be bonded to the reel body, which shortens the processing time of this step; 3. By setting a torsion spring, the elastic force provided by the torsion spring can make the suture straight after the entire puncture device is assembled; 4. Since the suture is hung on the winding post, when it is released, as long as it is rotated to a certain angle, it will slide off the winding post to separate from the reel body, so that the force of each release is almost the same and will not be affected by the bonding strength.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] Figures 1 to 8 Shown is an embodiment of the utility model.

[0030] Embodiment 1:

[0031] like Figure 1 , 2As shown, a reel assembly includes a disk-shaped reel body 1, a winding groove 2 is recessed around the side of the reel body 1, a winding post 3 is protruded from the bottom of the winding groove 2, an elastic groove 4 is recessed on one side of the reel body 1, a first rotating shaft 5 is protruded from the middle of the bottom of the elastic groove 4, a fixing post 6 is protruded from the bottom of the elastic groove 4, a torsion spring 7 is installed in the elastic groove 4, one end of the torsion spring 7 is connected to the winding post 3, and the other end extends out of the elastic groove 4. By providing the winding groove 2, when the suture 15 is wound on the reel body 1, it can be stored in the winding groove 2 and will not slip off the reel body 1. By setting the winding post 3, after the suture 15 passes through the rivet of the suture nail 11, the suture 15 is made into a ring shape by bonding or knotting, so that the suture 15 can be wound on the reel body 1 only after the suture 15 is hung on the winding post 3, and there is no need to wait for the suture 15 to be bonded to the reel body 1, which shortens the processing time of this step. By setting the torsion spring 7, the elastic force provided by the torsion spring 7 can make the suture 15 straight after the entire puncture device is assembled. Since the suture 15 is hung on the winding post 3, when the suture 15 is released, as long as it is rotated to a certain angle, the suture 15 will slide off the winding post 3 to separate the suture 15 from the reel body 1, so that the force of releasing the suture 15 each time is almost the same and will not be affected by the bonding strength.

[0032] The groove wall of the winding groove 2 is recessed in the direction away from the winding post 3 at the position of the winding post 3 to form an installation opening 8. By providing the installation opening 8, the width of the winding groove 2 at the position of the installation opening 8 can be greater than that of other positions of the winding groove 2, so that the assembler can hang the suture 15 on the winding post 3 more easily, and can assemble quickly, thereby improving the assembly efficiency.

[0033] The middle protrusion of the reel body 1 on the side away from the elastic groove 4 is provided with a second rotating shaft 9, and the axes of the first rotating shaft 5 and the second rotating shaft 9 are the same. By providing the second rotating shaft, when the reel body 1 is assembled into the installation cavity 14, the second rotating shaft 9 can be used to support the inner wall of the housing 13, so that the first rotating shaft 5 can be stably rotated and arranged in the rotating tube 16.

[0034] A plurality of ribs 10 are provided around the groove wall of the elastic groove 4 and protrude toward the middle of the elastic groove 4. By providing the ribs 10, a supporting force can be provided to the groove wall of the elastic groove 4, so that the groove wall of the elastic groove 4 still has sufficient strength even when the wall is thin. At the same time, with the help of the ribs 10 arranged at intervals, when installing the torsion spring 7, the ribs 10 can be used to support the outer wall of the torsion spring 7, so that the torsion spring 7 can be stably installed in the elastic groove 4. At the same time, compared with the torsion spring 7 being directly installed in contact with the groove wall of the elastic groove 4, it is more convenient to install in contact with multiple ribs 10, and the ribs 10 support the part of the torsion spring 7 to cause slight deformation, so that the torsion spring 7 is easier to assemble.

[0035] One end of the winding post 3 away from the bottom of the winding groove 2 protrudes from the notch of the winding groove 2, and the depth of the winding groove 2 at the position of the winding post 3 is lower than the depth of other positions of the winding groove 2. Such a configuration can make it easier to assemble the suture 15 on the winding post 3. After the suture 15 is hung on the winding post 3, when the suture 15 is wound around the winding groove 2, the suture 15 can fit the bottom of the winding post 3.

[0036] Embodiment 2:

[0037] like Figure 3-7As shown, a abdominal puncture device includes a sleeve 19, a connecting tube 20 is connected to the upper end of the sleeve 19, suture staples 11 are arranged on both sides of the inner wall of the lower end of the sleeve 19, a puncture cone assembly 12 is installed in the connecting tube 20 and the sleeve 19, and a staple pushing mechanism for pushing the suture staple 11 out of the sleeve 19 is arranged on the puncture cone assembly 12, a shell 13 is installed on the outer side of the connecting tube 20, an installation cavity 14 is formed between the shell 13 and the sleeve 19, and the installation cavity 14 is rotatably installed with a reel body 1 as in Example 1 on both sides of the opposite sides of the connecting tube 20, one end of the torsion spring 7 extending out of the elastic groove 4 is connected to the outer wall of the connecting tube 20, a suture thread 15 is wound in the winding groove 2, and the free end of the suture thread 15 passes through the shell 13 and is connected to the suture staple 11. A seal for sealing the gap between the connecting tube 20 and the puncture cone assembly 12 is installed in the connecting tube 20, so that when the puncture device is inserted into the abdominal cavity as a whole, the gas in the abdominal cavity will not escape from this position, resulting in a decrease in abdominal cavity pressure. The puncture cone assembly 12 and the nail pushing mechanism can adopt any form in the prior art, such as the nail pushing structure and puncture cone assembly in CN201480057286.5 mentioned in the background technology and the Chinese invention patent with application number 201910612495.6. In the above patents, different structures are adopted, but the puncture cone assembly and nail pushing mechanism with the same function are used to push the suture nail 11 out of the sleeve. The puncture cone assembly 12 and nail pushing mechanism of the utility model adopt any one of the puncture cone assemblies and nail pushing mechanisms in the above patents to realize the pushing out of the suture nail 11. A slot for fixing the suture staple 11 is provided on the inner wall of the sleeve 19. When the wound is not sutured, the suture staple 11 is fixed in the slot. When suturing is required, the suture staple 11 is pushed out of the sleeve by the staple pushing mechanism and enters the patient's body. Then, the suture thread 15 is tied on the outside of the patient's skin to pull the suture staple 11 to suture the wound.

[0038] The two opposite sides of the connecting pipe 20 are both provided with rotating pipes 16, and the first rotating shafts 5 of the two reel bodies 1 are respectively rotatably provided in the two rotating pipes 16. By providing the rotating pipes 16, the rotation stability of the reel body 1 can be improved.

[0039] A plurality of stoppers 17 are arranged around the rotating tube 16 on the side of the connecting tube 20, and the edge of the reel body 1 and the plurality of stoppers 17 are slidably fitted; a clamping groove 18 is arranged on the outer wall of the connecting tube 20, and one end of the torsion spring 7 extending out of the elastic groove 4 is connected to the clamping groove 18. By providing the stoppers 17, the stability of the installation and rotation of the reel body 1 can be further improved. When the reel body 1 rotates, the plurality of stoppers 17 can fit the edge of the reel body 1, so that the reel body 1 will not shake when rotating. By providing the clamping groove 18, the end of the torsion spring 7 extending out of the elastic groove 4 can be fixed, so that the suture 15 can be straightened by means of the elastic potential energy generated by the rotation of the torsion spring 7.
