Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary medical devices, and particularly to an inner clip assembly device for a hemostatic clip. Background Art

[0002] In surgical operations, hemostatic clips are often used to clamp human blood vessels and tissues to achieve hemostasis. Currently, hemostatic clips are mainly made of metal, plastic, and absorbable materials. When clamping, the hemostatic clip needs to be assisted by an applicator, and the stability of the applicator directly affects the effect of the hemostatic clip and the surgical efficiency. Currently, the applicators for metal clips and plastic clips are mainly metal applicators. The absorbable hemostatic clip consists of an inner clip and an outer clip. Before clamping the blood vessel, the inner clip is in an open form, so the material of the inner clip must be a soft material to ensure that it can be easily closed under the action of the outer clip.

[0003] The Chinese patent with the authorization announcement number CN 206342515 U discloses a hemostatic clip outer sleeve, which can well improve the surgical efficiency. However, because the material of the inner hemostatic clip is weak, the inner clip is assembled by a forced insertion method during the assembly process, which is easy to cause wear of the inner clip. During the surgical process, the inner clip is prone to deformation and wear, resulting in slippage during the clamping process; in addition, there are some simple assembly devices, although they can achieve the purpose of inner clip assembly, but have relatively high requirements for the assembly personnel. Slight negligence of the assembly personnel is likely to cause poor product assembly. At the same time, the operator needs to continuously contact the product, increasing the risk of product contamination. Summary of the Invention

[0037] Example 1:

[0038] This example provides a hemostatic clip inner clip assembly device for assembling the hemostatic clip sleeve 7 and the hemostatic clip inner clip 8. On both sides of one end of the hemostatic clip sleeve 7, card slots 7-1 are symmetrically arranged. The other end is an open structure and is provided with a positioning elastic piece 7-2. On the top surface of the positioning elastic piece 7-2, there is a card slot 7-3.

[0039] As Figures 1 - 3 shown, the hemostatic clip inner clip assembly device of this example includes a base 1, a slide block assembly 2, a feeding mechanism 3, an actuator 4, and an auxiliary mechanism 5. The slide block assembly 2, the feeding mechanism 3, the actuator 4, and the auxiliary mechanism 5 are all installed on the base 1.

[0040] Specifically, as shown in FIGS. 4(a) and 4(b), the base 1 includes a base body which consists of a first part, a second part and a third part connected as a whole. Among them, the first part and the third part are convex structures, and the second part is a groove structure, so that the base body forms a "concave" shape structure.

[0041] The first part is provided with a first installation groove 1-8 and a second installation groove 1-9. The first installation groove 1-8 is used to install the auxiliary mechanism 5, and the second installation groove 1-9 cooperates with the second part and the third part to install the hemostatic clip sleeve 7. As shown in FIGS. 4(a) and 4(b), the first installation groove 1-8 and the second installation groove 1-9 are arranged at intervals along the length direction of the base body, and the two are separated by a partition 1-10.

[0042] Both ends of the first installation groove 1-8 are sealing ends. One end of the second installation groove 1-9 forms a sealing end through the partition 1-10, and the other end is an open end, that is, it penetrates the first part. Limiting holes 1-2 are correspondingly opened at both ends of the first installation groove 1-8, so that the auxiliary mechanism 5 passes through the limiting holes 1-2. The bottom surface of the second installation groove 1-9 is an arc surface, and a support ring 1-7 is provided at its open end to support one end of the hemostatic clip sleeve 7. Limiting protrusions 1-3 are symmetrically arranged on the inner wall of the second installation groove 1-9 and are used to cooperate with the clamping grooves 7-1 on both sides of the hemostatic clip sleeve 7.

[0043] As shown in FIG. 4(a), a plurality of screw holes 1-4 are provided in the second part, and the whole device is fixed on the tabletop or other supporting devices by screws to increase the stability of the device.

[0044] A first guiding chute and a second guiding chute are provided in the third part from one end close to the second part to the other end. The first guiding chute and the second guiding chute are connected and penetrate the third part. The width of the first guiding chute is smaller than that of the second guiding chute, and the two form a convex shape structure.

[0045] As Figure 2 and Figure 3 shown, the first guiding chute cooperates with the other end of the hemostatic clip sleeve 7, and clamping buckles 1-6 are symmetrically arranged on the inner wall of the first guiding chute. As Figure 10 shown, the clamping buckle 1-6 adopts a form of an inclined plane inner groove, so that the hemostatic clip sleeve can be clamped after simple pressing, restricting the up and down movement of the hemostatic clip sleeve 7.

[0046] A limiting groove 1-5 is provided on the bottom surface of the first guiding chute to limit the linear movement of the inner clip of the hemostatic clip when sliding. A slider assembly 2 is provided in the second guiding chute, and sliding grooves 1-1 are symmetrically arranged on the inner wall of the second guiding chute. The slider assembly 2 and the sliding grooves 1-1 cooperate to form a sliding pair. A baffle 6 is detachably connected to one end of the third part corresponding to the second guiding chute.

[0047] The slider assembly 2 is slidably connected to the base 1, and its functions are: first, to compensate for the processing error of the parts; second, to play a horizontal extrusion role when the hemostatic clip sleeve 7 presses the buckle 1-6, ensuring that the hemostatic clip sleeve 7 and the side wall of the slider assembly 2 are in seamless extrusion contact.

[0048] like Figure 5 As shown, the slider assembly 2 includes a positioning slider 2-4, a stopper 2-5, and a limit plate 2-3. The positioning slider 2-4 is provided with a feed trough 2-2, which forms a U-shaped structure of the positioning slider 2-4, and the feed trough 2-2 does not penetrate the positioning slider 2-4 in the vertical direction; the stopper 2-5 is symmetrically arranged on the side wall of the open end of the positioning slider 2-4.

[0049] In this embodiment, a dovetail groove is provided on the side wall of the open end of the positioning slider 2-4, and the stopper 2-5 has a protrusion that cooperates with the dovetail groove to achieve a fixed connection with the positioning slider 2-4; a gap is formed between the two stoppers 2-5 for the actuator 4 to pass through.

[0050] like Figure 5 As shown, the open end face of the positioning slider 2-4 is provided with a blind hole 2-1, within which a first compression spring 9 is mounted. The first compression spring 9 is connected to the baffle 6. The slider assembly 2 elastically slides along the slide groove 1-1 under the action of the baffle 6 and the first compression spring 9. The closed end of the positioning slider 2-4 is provided with an outlet 2-6, which is used to connect the inner clip 8 of a single hemostatic clip with the hemostatic clip sleeve 7. Beveled surfaces are provided on both sides of the outlet 2-6 to facilitate the insertion of the hemostatic clip sleeve 7. A fixing groove 2-7 is provided on the upper surface of the closed end, through which the feed mechanism 3 is fixed.

[0051] The feed trough 2-2 is provided with a feed mechanism 3 and an inner hemostatic clamp 8. The inner wall of the feed trough 2-2 is symmetrically provided with limit plates 2-3. The limit plates 2-3 are arranged vertically and have a certain height. The space between the two limit plates 2-3 forms a limit space for the inner hemostatic clamp 8 to control the opening angle of the inner hemostatic clamp 8. The limit plates 2-3 are fixedly connected to the feed trough 2-2, for example, by glue.

[0052] In this embodiment, the cross section of the feeding trough 2-2 is an isosceles trapezoidal structure, that is, the range gradually decreases from the end where the stopper 2-5 is located to the other end.

[0053] like Figure 2As shown in Figures 6(a) and 6(b), the feeding mechanism 3 includes a conveying chute 3-3 and a counterweight 3-4. The conveying chute 3-3 has a certain height. The conveying chute 3-3 is provided with a through channel 3-1 in the height direction. Guide chutes 3-5 are symmetrically arranged on both sides of the conveying chute 3-3. The bottom of the conveying chute 3-3 has a limit opening 3-2. The top of the guide chute 3-5 is closed, and the bottom is communicated with the limit opening 3-2. The whole guide chute 3-5 is communicated with the internal channel 3-1, so that the inner clip 8 of the hemostatic clip is placed into the conveying chute 3-3 from the limit opening 3-2, and the inner clip legs 8-2 of the inner clip 8 of the hemostatic clip extend out from the guide chute 3-5, and the head of the inner clip 8 of the hemostatic clip is located in the channel 3-1.

[0054] The counterweight 3-4 is placed from the top of the channel 3-1. When the inner clip 8 of the hemostatic clip slides down from the feeding mechanism 3 under the action of the counterweight 3-1, it is in the undeformed state of the inner clip 8 of the hemostatic clip, ensuring that the side of the inner clip 8 of the hemostatic clip is not stressed and can slide down easily.

[0055] The conveying chute 3-3 has a side portion adapted to the shape of the fixing groove 2-7 to fix the conveying chute 3-3 through the fixing groove 2-7, so that a single inner clip 8 of the hemostatic clip falls from the limit opening 3-2 into the feeding chute 2-2 and corresponds to the outlet 2-6.

[0056] An actuating mechanism 4 is provided on the side of the conveying chute 3-3 opposite to its side portion. The actuating mechanism 4 is used to push the inner clip 8 of the hemostatic clip that has fallen into the feeding chute 2-2 to move it towards one end close to the hemostatic clip sleeve 7. As Figure 7 shown, the actuating mechanism 4 includes an inner clip mounting shaft 4-4 and a boosting handle 4-2. The boosting handle 4-2 is connected to one end of the inner clip mounting shaft 4-4. The baffle 6 is provided with a card slot corresponding to the gap between the two stoppers 2-5. The inner clip mounting shaft 4-4 passes through the card slot, so that the boosting handle 4-2 is located outside the baffle 6.

[0057] The shape of the boosting handle 4-2 can be set according to the actual situation. For the convenience of operation, the boosting handle 4-2 in this embodiment is set as a disc-shaped structure.

[0058] A chute 4-1 is provided on the bottom surface of the inner clip mounting shaft 4-4. The inner clip mounting shaft 4-4 is slidably connected to the positioning slider 2-4 through the chute 4-`1, so that the inner clip mounting shaft 4-4 can move along the positioning slider 2-4. Limiting portions 4-3 are symmetrically arranged at a certain length from the boosting handle 4-2 on the inner clip mounting shaft 4-4. The push block 4-6 is connected through the limiting portions 4-3. One end of a tension spring 4-5 is connected to the side of the limiting portion 4-3 facing the boosting handle 4-2, and the other end of the tension spring 4-5 is connected to the stopper 2-5. The tension spring 4-5 forms a limit on the moving stroke of the inner clip mounting shaft 4-4.

[0059] In this embodiment, the limiting portion 4-3 and the inner clamp mounting shaft 4-4 form a cross-shaped structure. A cavity is provided inside the limiting portion 4-3, and a plurality of second compression springs 4-7 are provided in the cavity. One end of the second compression spring 4-7 is fixed to the inner wall of the cavity, and the other end is connected to the push block 4-6; under the action of the second compression spring 4-7, the push block 4-6 can slide elastically along the cavity.

[0060] like Figure 7 As shown, the push block 4-6 includes a mounting portion and a guide portion connected as one body, forming an L-shaped structure. One end of the mounting portion is connected to the second compression spring 4-7, and the other end is connected to the guide portion. The end of the mounting portion connected to the second compression spring 4-7 is located in the cavity, and has lugs on both sides of this end to prevent the mounting portion from falling out of the cavity. The mounting portion is limited on both sides by fixed plates 4-8 connected to the end face of the limiting portion 4-3. Furthermore, the fixed plates 4-8 use screws to press the two lugs on both sides of the push block 4-6, preventing the push block 4-6 from popping out of the sliding groove on the side of the inner clamp mounting shaft 4-4 under the action of the spring.

[0061] The outer end surface of the guide portion is an inclined surface, and is inclined from one end close to the booster handle 4-2 to the other end, so that the push block 4-6 can cooperate with the inner clamping leg 8-2 and can push the inner clamping legs 8-2 of different sizes to move.

[0062] The auxiliary mechanism 5 is used to push the hemostatic clip sleeve 7 to move toward the side where the hemostatic clip inner clip 8 is located. Figure 8 As shown, the auxiliary mechanism 5 includes a pushing part and a thrust part. The pushing part includes a push rod 5-1, a third compression spring 5-2 and a retaining spring 5-3. The push rod 5-1 is arranged along the length direction of the base 1 and passes through the limiting holes 1-2 of the base 1 in sequence, so that one end of the push rod 5-1 is located in the second mounting groove 1-9 of the base 1, and the other end is located on the outside of the base 1.

[0063] In this embodiment, the cross section of the push rod 5 - 2 is a cross-shaped structure, and the shape of the limiting hole 1 - 2 is suitable for the cross section of the push rod 5 - 2.

[0064] like Figure 3 As shown, the third compression spring 5-2 is sleeved on the rod section of the push rod 5-1 located in the first mounting groove 1-8. One end of the third compression spring 5-2 is fixed to the push rod 5-1 through the clamping spring 5-3, and the other end abuts against the inner wall of the first mounting groove 1-8. A grip portion is provided at the end of the push rod 5-1 located outside the base 1 to facilitate operation. Figure 8 As shown, a thrust groove 5-7 is provided at a certain distance between the bottom of the push rod 5-1 and the grip portion, and the thrust groove 5-7 cooperates with the thrust portion to limit the movement of the push rod 5-1.

[0065] like Figure 8 and Figure 9As shown, the thrust part includes a thrust block 5-4, a spring-loaded button 5-6, and a fourth compression spring 5-5. The thrust block 5-4 has an L-shaped structure, including a vertical section and a horizontal section. The vertical section is located below the push rod 5-1, and the horizontal section is located on one side of the push rod 5-1. When the thrust block 5-4 is engaged in the thrust slot 5-7, the push rod 5-1 cannot move. As Figure 3 shown in FIGS. Figure 3 and 4(a), the base 1 is provided with a U-shaped accommodation space at the end corresponding to the first mounting groove 1-8, and the thrust block 5-4 is arranged in the U-shaped accommodation space.

[0066] A threaded hole is provided in the vertical section of the thrust block 5-4. One end of the spring-loaded button 5-6 is connected to the threaded hole, and the other end has a convex portion. A counterbore is longitudinally formed at the end of the base 1. The spring-loaded button 5-6 is arranged in the counterbore, and its head is located outside the base 1. The spring-loaded button 5-6 is sleeved with a fourth compression spring 5-5. The fourth compression spring 5-5 is arranged in the counterbore, and its top abuts against the bottom surface of the convex portion of the spring-loaded button 5-6.

[0067] As Figure 9 shown, in the initial state (unpressed state) of the spring-loaded button 5-6, the thrust block 5-4 abuts against the bottom surface of the push rod 5-1. After pressing the spring-loaded button 5-6, when the thrust slot 5-7 corresponds to the thrust block 5-4, releasing the spring-loaded button 5- can cause the thrust block 5-4 to be engaged in the thrust slot 5-7.

[0068] The working principle of this embodiment is as follows:

[0069] One end of the two slots 7-1 on both sides of the hemostatic clip sleeve 7 is clamped on the corresponding limit protrusion 1-3, and the other end of the hemostatic clip sleeve 7 is rotated along the two limit protrusions 1-3 and clamped on one side of the positioning slider 2-4. Push the push rod 5-1 of the auxiliary mechanism 5 to make the thrust block 5-4 just clamped in the thrust slot 5-1 of the push rod 5-1. At this time, the other end of the push rod 5-1 is inserted into the inner groove of the hemostatic clip sleeve 7. The width of the push rod 5-1 is greater than the width between the two clamping elastic pieces 7-2 of the hemostatic clip sleeve 7, and under the action of force, the two clamping elastic pieces 7-2 on the hemostatic clip sleeve 7 are opened at a certain angle.

[0070] Then push the inner clip mounting shaft 4-4. Under the action of the thrust, push the hemostatic clip inner clip 8 forward. When the push block 4-6 contacts the leg 8-2 of the hemostatic clip inner clip, the inner clip mounting shaft 4-4 simultaneously touches the position 8-1 of the hemostatic clip inner clip, and at the same time, the upper surface of the inner clip mounting shaft 4-4 supports the other hemostatic clip inner clip 8 to prevent it from sliding down.

[0071] As the orbit becomes smaller, the push block 4-6 compresses inward under the action of the second compression spring 4-7. When the front end face of the inner clamp mounting shaft 4-4 fits against the inner end face of the positioning slider 2-4, the clamping position 8-1 of the hemostatic clip inner clamp 8 is exactly aligned with the card slot 7-3 of the hemostatic clip sleeve 7. At this time, press the elastic pressing button 5-6, the push rod 5-1 returns to its original position under the action of the third compression spring 5-2. At the same time, the clamping elastic piece 7-2 rebounds to its initial position to clamp the hemostatic clip inner clamp 8. At the same time, release the left hand and the actuating mechanism 4 returns to its original position.

[0072] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
