Description

Technical Field

[0001] The utility model relates to the technical field of abdominal puncture device processing, in particular to a rivet sleeve assembly device with a fixed structure. Background Art

[0002] Laparoscopic surgery has gradually replaced traditional surgery due to its advantages of 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 an incision in the patient's abdomen and performing the surgery under laparoscope observation. Fascia suture is required after the surgery.

[0003] At present, most of the above operations are performed with abdominal puncture devices. For example, the Chinese invention patent with patent application number CN202111344054.6 discloses a push-pin suturing structure for a laparoscopic puncture suturing device, the Chinese invention patent with patent application number CN201480057286.5 for trocar and wound closure device, and the Chinese utility model with application number CN202320262674.3 discloses a fascia suturing puncture device. All of them are based on the original abdominal puncture device, and a mechanism for suturing the wound is added. After the operation is completed, the patient's wound can be quickly sutured, which can achieve rapid suturing of the wound. Among them, the patent CN202320262674.3 discloses “S1. During the abdominal surgery, first install the anchor with wire on the anchor groove, make an incision in the abdominal cavity with a scalpel, insert the assembled puncture sheath assembly and puncture vertebra assembly into the incision, and pull the puncture device outward so that the puncture vertebra head spurt contacts the abdominal fascia; S2. Press the needle core button and pull up the needle seat. With the sound of the shrapnel popping out, the puncture needle core can be pressed downward. When the force is unloaded, the anchor has penetrated the fascia. Under the action of the spring, the shrapnel and the needle rod return to the needle seat; S3. At this time, continue to push the puncture device into the body to let the puncture vertebra head spurt leave the fascia. By pressing the buckle, the puncture vertebral assembly can be pulled out, and the remaining puncture sheath assembly remains on the abdominal incision. According to the needs of abdominal surgery, the abdominal cavity can be inflated through the air valve to ensure surgical space. Different surgical instruments can be inserted into the puncture sheath assembly for surgery. After the operation, the puncture sheath assembly can be directly pulled out. Since the wire anchor is left in the fascia, the suture can be knotted and the fascia can be sutured. Both the suture and the anchor are absorbable materials in the body, which can effectively solve the problem of fascia suturing. "When installing the rivet, since the rivet has been assembled with the suture, one end of the suture is connected to the rivet, and the other end needs to be fixed to the head tube seat of the puncture device. Before installing the rivet,

[0004] It can be seen from the above-mentioned patent disclosure that when using a puncture device to suture a wound, rivets and sutures need to be installed on the puncture device first. In the prior art, the rivets of some puncture devices are installed before use, and most of them are pre-installed on the puncture device during the production process, so that they can be used directly when used. At present, when processing puncture devices, most rivet installations are purely manual, and some simple tools are used for installation. During installation, the sleeve needs to be fixed to the tool for installation, such as by fixing the sleeve vertically with a vertical pole before installation. However, in order to enable the sleeve to be smoothly mounted on the vertical pole, the diameter of most vertical poles is smaller than the inner diameter of the sleeve, which causes the sleeve to shake easily during installation, thereby affecting the operating efficiency.

[0005] Based on the above reasons, the utility model proposes a rivet sleeve assembly device with a fixed structure, which can facilitate processing personnel to quickly install the rivet on the sleeve of the puncture device. Utility Model Content

DETAILED DESCRIPTION

[0024] 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.

[0025] Figures 1 to 6 Shown is an embodiment of the utility model.

[0026] Embodiment 1:

[0027] like Figure 1 , 2As shown, a rivet sleeve assembly device with a fixed structure includes a base 1, a vertical rod 2 and a push needle head 3. The vertical rod 2 is vertically arranged on the upper side of the base 1. The two opposite sides of the upper end of the vertical rod 2 are recessed with rivet guide grooves 4. The lower end of the push needle head 3 is provided with a pressing block 5 matching the rivet guide grooves 4. A bar hole 18 is provided in the middle of the vertical rod 2, and a support plate 19 is detachably installed in the bar hole 18. The two opposite sides of the support plate 19 are protruding from the two ends of the bar hole 18. When using the device, by inserting the sleeve 15 of the puncture device into the vertical rod 2, aligning the rivet 17 groove on the sleeve 15 with the rivet guide groove 4 on the vertical rod 2, and then putting the rivet 17 into the rivet 17 groove, and then aligning the pressing block 5 on the push needle head 3 with the rivet 17 and pressing down, the rivet 17 can be stably and firmly installed in the rivet 17 groove of the sleeve 15. The rivet guide groove 4 can play a guiding role when the push pin 3 pushes the rivet 17 to be installed in the rivet 17 groove on the sleeve 15. The rivet guide groove 4 fits the side of the rivet 17 to limit the rivet 17, so that the rivet 17 can be accurately stuck in the rivet 17 groove of the sleeve 15. The push pin 3 and the pressure block 5 replace the finger pressing to avoid the operator's fingers from being injured. By setting the base 1, it can be ensured that when the device is used, the vertical rod 2 can remain in a vertical state, providing stability for the entire device.

[0028] like Figure 2 As shown, the support plate 19 is installed in the strip hole 18 through the fixing rod 20, the side of the vertical rod 2 is provided with a first fixing hole 21 connected to the strip hole 18, and the middle of the support plate 19 is provided with a second fixing hole 22 that passes through both sides. When the first fixing hole 21 and the second fixing hole 22 are aligned, the fixing rod 20 passes through the first fixing hole 21 and the second fixing hole 22 in sequence. When the support plate 19 is installed in this way, the support plate 19 is vertically inserted into the strip hole 18, so that the first fixing hole 21 and the second fixing hole 22 are aligned, and then the fixing rod 20 is inserted from the first fixing hole 21 and then inserted into the second fixing hole 22, so that the support plate 19 can be fixed in the strip hole 18. There are more than two fixing rods 20, the first fixing hole 21 and the second fixing hole 22, which can improve the stability of the installation of the support plate 19. Threads can also be provided on the inner wall of the first fixing hole 21 or the second fixing hole 22, and matching threads are provided on the fixing rod 20, and the fixing rod 20 can be prevented from falling off by thread fixing.

[0029] A guide hole 6 is vertically provided at the upper end of the vertical rod 2, and a guide rod 7 matching the guide hole 6 is provided at the lower end of the push pin 3. By providing the guide hole 6 and the guide rod 7, when the push pin 3 pushes the rivet 17 into the rivet 17 groove of the sleeve 15, the guide rod 7 is inserted into the guide hole 6, which can guide the pressing direction of the push pin 3, so that the rivet 17 can be pressed from the vertical direction.

[0030] There are two or more guide holes 6 and guide rods 7. Through two or more guide holes 6 and guide rods 7, the position of the pressing block 5 can be well limited, so that the pressing block 5 can accurately align with the rivet guide groove 4 during the pressing process, thereby pressing the rivet 17.

[0031] like Figure 5 As shown, a mounting hole 8 is provided at the lower end of the push pin head 3, one end of the guide rod 7 is inserted into the mounting hole 8, and the other end is placed below the push pin head 3. By providing the mounting hole 8, it is easy to install the guide rod 7, and the guide rod 7 can be installed in the mounting hole 8 by screwing or bonding. When the guide rod 7 is used for a long time or the push pin head 3 falls off, the guide rod 7 may be bent, which affects the use. The damaged guide rod 7 can be removed from the mounting hole 8 and replaced with a new guide rod 7 for use.

[0032] The vertical rod 2 is slidably sleeved with a cushion block 9. By providing the cushion block 9, since the sleeve 15 is inverted when the rivet 17 is assembled, Figure 6 As shown, the pad 9 can support the inside of the head of the sleeve 15, and the pads 9 of different thicknesses can also adjust the height of the sleeve 15 to adapt to sleeves 15 of different lengths, so that the rivet 17 groove of the sleeve 15 can be accurately aligned with the rivet guide groove 4. When the rivet 17 is installed, one end of the suture 16 is fixed to the rivet 17, and the other end is fixed to the head of the sleeve 15, so that when in use, the rivet 17 can drive the suture 16 to cooperate with the wound to fix it.

[0033] Two grooves 10 are provided on the lower side of the pressing block 5. When the push pin 3 is assembled on the upper end of the vertical rod 2, the two grooves 10 correspond to the two rivet guide grooves 4 respectively. By providing the grooves 10, when the rivet 17 is pressed, the two grooves 10 can limit the sharp parts of the two rivets 17. The sharp parts of the rivets 17 are placed in the grooves 10 and pressed down, so that the rivets 17 can be pressed down vertically smoothly.

[0034] like Figure 4As shown, the vertical pole 2 is vertically arranged on the upper side of the base 1 through a bolt 11, and the base 1 is provided with a through hole penetrating the upper and lower sides, and the lower end of the vertical pole 2 is provided with a threaded hole 12. When the threaded hole 12 and the through hole are aligned, the bolt 11 passes through the through hole from the lower side of the base 1 and is threadedly matched with the threaded hole 12; the lower side of the base 1 is provided with a receiving groove 13 for receiving the nut of the bolt 11 around the through hole. By providing the bolt 11, the vertical pole 2 can be stably installed on the base 1. By providing the receiving groove 13, the nut of the bolt 11 can be received, so that after installation, the nut of the bolt 11 will not protrude from the lower side of the base 1, so that the base 1 can be placed stably.

[0035] like Figure 1 As shown, a tension cap 23 is installed at the upper end of the push needle 3, and hooks 25 are installed on the opposite sides of the tension cap 23 through elastic members 24. By setting the tension cap 23 and the hook 25, it can play an auxiliary installation role. An installed puncture device, as shown in the patent with application number CN202320262674.3, one end of the suture 16 is connected to the rivet 17, and the other end is fixed to the tension mechanism in the head (tube seat) of the puncture device. The tension structure straightens the suture 16 through a spring, a torsion spring or any other elastic component, and puts the suture 16 in a tensioned state, so that when the rivet 17 and the suture 16 are used for suturing later, the nails can be accurately inserted and knotted, so that the wound is sutured firmly, and the loose suture 16 is prevented from causing loose sutures and bleeding points. Therefore, when installing the rivet 17, since one end of the suture 16 has been fixed to the tension structure, if the rivet 17 needs to be placed in the rivet groove of the sleeve 15, the suture 16 needs to be tightened, and a part of the suture 16 needs to be pulled out from the head of the puncture device to meet the installation of the rivet 17. At this time, the suture 16 is straightened and tightened. If the operator uses manual operation, it is troublesome to put it into the rivet groove due to the tension of the tensioning mechanism, which affects the operation of the operator. Therefore, the utility model is used to set the tension cap 23 and the hook 25 to cooperate with the installation of the rivet 17. Specifically, when in use, the sleeve is inverted and inserted from the upper end of the vertical rod 2. At this time, the lower end of the sleeve faces upward. When the lower end of the sleeve moves to the hook 25, the sutures 16 on both sides are hung on the hook 25, so that the rivet 17 and the hook 25 are fitted to use the hook 25 instead of manual to straighten the suture 16. The operator only needs to push the rivet 17 to the position of the rivet groove, and then press the rivet 17 into the rivet groove by the pressing block.

[0036] The upper end of the push pin 3 is provided with an insertion hole 26, and the lower end of the tension cap 23 is provided with an insertion rod 27 matching the insertion hole 26. By providing the insertion hole 26 and the insertion rod 27, the tension cap 23 can be easily installed, and the insertion hole 26 and the insertion rod 27 can be fixed by threads.

[0037] The two opposite sides of the push needle head 3 are both provided with planes 14, and anti-skid patterns are provided on the planes 14. By providing the planes 14 and the anti-skid patterns, when the operator takes and uses the push needle head 3, it is easier to clamp it and prevent the push needle head 3 from falling.

[0038] Although the utility model is described herein with reference to a plurality of illustrative embodiments of the utility model, it should be understood that those skilled in the art may devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, within the scope of the disclosure, drawings, and claims of the present application, various modifications and improvements may be made to the components and / or layout of the subject combination layout. In addition to the modifications and improvements made to the components and / or layout, other uses will also be apparent to those skilled in the art.
