Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a continuous clip applier. Background Art

[0002] Clip applicators are a commonly used medical device, usually used in needle-held suture operations, used to clamp blood vessels and stop bleeding, so they are sometimes called hemostatic forceps. In medical surgery, especially minimally invasive techniques, when a patient is bleeding, after taking hemostatic drugs, a clip applicator is used to clamp the blood vessel artery to prevent blood from flowing out. The principle of a clip applicator is the same as that of a clamp, but it is sterilized. Clip applicators can be large, small, with teeth, without teeth, straight, or curved. Different types of clip applicators are selected according to different operating parts.

[0003] Since the clip applier is used during the surgical operation, for example, the bleeding site or the bleeding point that has been seen is clamped first. Therefore, the clamping of the bleeding point requires accuracy, and it is best to succeed in one go, and not to bring too much healthy tissue into it. Since the operating space of this type of minimally invasive surgery is small and complex, the instrument has a small travel range and high precision requirements. Therefore, traditional technology tends to improve the convenience of operation, precision and structure of the clip applier.

[0004] For example, Chinese patent application No. 201711310132.4 discloses a minimally invasive hemostatic forceps that is easy to disassemble and assemble, which includes a fixed handle, a movable handle, a fixed clamp and a movable clamp, wherein the movable handle is drivingly connected to one end of a steel wire rope inserted into the fixed handle through a transmission connecting piece, and the other end of the steel wire rope is drivingly connected to the movable clamp rotatably connected to the fixed clamp. The steel wire rope is connected to a steel wire rope connecting rod that is slidably connected in the fixed handle, a pull rod pin at one end of the transmission connecting piece is clamped on the steel wire rope connecting rod, and the other end of the transmission connecting piece is rotatably connected to the movable handle, and a torsion spring is provided between the transmission connecting piece and the movable handle to clamp the pull rod pin to the steel wire rope connecting rod. In this patent application, it is pointed out that the hemostatic forceps is easy to disassemble and clean, and the operation is simple and not complicated. The hemostatic forceps can be equipped with different types of jaws on a handle to meet the needs of medical staff, achieving the function of one handle for multiple uses. Disassembly can also make the instrument cleaning more thorough, and at the same time make it easier for medical staff to use. The clamping force adjustment is reliable and accurate, and the control is flexible, thereby improving the efficiency of minimally invasive surgery.

[0005] However, both the improved structure in the above patent application and the traditional hemostatic forceps structure inevitably encounter a practical problem. That is, during the surgical operation, generally not only one blood vessel needs to be clamped to stop bleeding, but two, three, or even more blood vessels need to be clamped. However, the existing hemostatic forceps can only carry one plastic clip, and the clips are all disposable. As in the structure disclosed in the above patent application, the clamp has a long connecting rod. Therefore, every time a surgical hemostasis is performed, such a long clamp needs to be inserted into the patient's body, which is obviously extremely disadvantageous.

[0006] Although the traditional single-operation clip applicator has many structural improvements, it is a single operation and inevitably has the following shortcomings: On the one hand, when multiple blood vessels need to be hemostatic at the same time, multiple operations are required, which will inevitably prolong the operation time. It should be noted that operation time is of the essence, and current medical devices are all based on saving doctors' operation time as the top priority. Because the longer the time, the easier it is for doctors to get tired, and the greater the impact on the patient's body. On the other hand, the frequent entry and exit of the clip applicator will greatly increase the risk of surgery and the probability of infection. In addition, during the operation, the problem that doctors usually encounter in the process of hemostasis is that multiple blood vessels are bleeding. Usually, when the clip applicator is put in for the second time, the original blood vessels are blurred due to bleeding and are difficult to find. Sometimes they need to be cleaned again to find the blood vessels that need to be hemostatic, which takes more time. Patients will also need to bleed too much, and their physical fitness will be overdrawn, affecting the progress of health recovery. Summary of the invention

[0026] The present invention will be described in detail below with reference to specific embodiments and accompanying drawings.

[0027] See also Figure 1 and Figure 2 , showing a continuous-fire clamp applier 100 provided by an embodiment of the present invention, comprising a pushing handle 10, a tube rod 20, a clamp head 30 mounted on the front end of the tube rod 20, a push-pull rod 12 driven by the pushing handle 10, a feeding device 40 and a storage compartment 50, wherein the storage compartment 50 has a front end movably connected to the clamp head 30 and a rear end opposite to the front end, one end of the push-pull rod 12 is connected to the pushing handle 10, and the other end is connected to the rear end of the storage compartment 50 and acts on the storage compartment 50 to open or clamp the clamp head 30, the feeding device 40 includes a transmission member 41 and a driving member 42 for driving the transmission member 41 to move, the storage compartment 50 has a plurality of clamps for clamping blood vessels, and the transmission member 41 extends into the storage compartment 50 to push the clamps into the clamp head 30.

[0028] Preferably, the storage compartment 50 includes a front compartment 51 and a rear compartment 55, the rear compartment 55 having a front end close to the pliers head 30 and a rear end away from the pliers head 30, the front compartment 51 is arranged on the front end inner wall of the rear compartment 55 and extends from the front end of the rear compartment 55 to the opening of the pliers head 30, and the transmission member 41 extends into the front compartment 51.

[0029] like Figure 2 As shown, the front end of the rear compartment 55 extends forward with an upper lip piece 56 and a lower lip piece 57 which are parallel to each other and spaced apart from each other, and the upper lip piece 56 and the lower lip piece 57 face each other and extend with convex shafts 561 and 562. Figure 2 and 3 As shown, the end of the clamp head 30 near the storage compartment 50 has an oblique groove 35, and the protruding shafts 561 and 562 are inserted into the oblique groove 35. The end of the clamp head 30 is clamped between the outer wall of the front compartment 51 and the inner wall of the rear compartment 55, and the protruding shafts 561 and 562 move in the oblique groove 35 to drive the clamp head 30 to open or clamp. Therefore, the protruding shafts 561 and 562 are inserted into the oblique groove 35, and the two clamp arms 31 and 32 are pivoted with the protruding shafts 561 and 562. In this way, the rotating shaft 23 acts as a rotating fulcrum to pull the protruding shafts 561 and 571 of the storage compartment 50, and the two clamp arms 31 and 32 perform a clamping action, while the storage compartment 50 is a backward pulling action, so the front compartment 51 is retracted at this time, which is equivalent to avoiding the clamp 60. In this way, before clamping, the end of the clamp 60 can still partially stay in the front end of the front compartment 51. When pulled back, the front compartment 51 retracts and completely releases the clamp 60, making it easier for the two clamp arms 31 and 32 to perform the clamping action.

[0030] like Figure 2 and 3As shown, the front end of the pipe rod 20 is provided with an upper mounting plate 21 and a lower mounting plate 22, and the two mounting plates 21, 22 are each equipped with a rotating shaft 23. The clamp head 30 includes a pair of clamp arms, as shown in the figure, a first clamp arm 31 and a second clamp arm 32, and the rear ends of the pair of clamp arms 31 and 32 are connected to the pipe rod 20 and are provided with an axial hole 36 for mounting the rotating shaft 23 at the rear ends, so that the clamp head 30 rotates around the rotating shaft 23, and the pair of clamp arms 31, 32 are clamped and released under the pulling of the rear compartment 55.

[0031] Preferably, the front compartment 51 has a front hatch 510 and a rear hatch 519 close to the pliers head 30, and side grooves 58 are respectively opened on both sides of the rear end of the rear compartment 55, and each side groove 58 extends from the hatch at the rear end of the rear compartment 55 to the rear hatch 519 of the front compartment 51, and the transmission member 41 has a hollow cavity for accommodating the push-pull rod 12, and side strips 48 are axially extended on both sides of the front end of the hollow cavity of the transmission member 41, and the two side strips 48 are correspondingly inserted into the two side grooves 58 of the rear compartment 55, and the push-pull rod 12 further extends between the side strips 48 and is connected to the rear end of the rear compartment 55.

[0032] like Figure 2 and 3 As shown, further, a mounting groove 59 is dug on the inner wall of the rear end of the rear compartment 55, and the burst clamp includes a push-pull rod 12, one end of which is tightly coupled to the mounting groove 59, and the push-pull action of the push-pull rod 12 drives the clamp head 30 to clamp and release. The front end of the push-pull rod 12 can be installed in the mounting groove 59 by interference fit, so that the push-pull rod 12 is tightly coupled to the rear end of the rear compartment 55, and the two move synchronously.

[0033] The storage compartment 50 and the transmission member 41 are preferably tubular, and the side groove 58 is preferably formed by cutting the side of the rear compartment 55. The two side grooves 58 are axially symmetrical and communicate with the space inside the compartment. The side strip 48 can be formed by cutting the upper and lower parts of the tubular structure, and the side strip 48 is equivalent to the complementary part of the tubular structure of the side groove 58. In other words, the storage compartment 50 and the transmission member 41 are both tubular and have equal diameters. The side strip 48 is inserted into the side groove 58 and merged into a tube, which makes the structure more compact and improves the accuracy of the instrument. In addition, during the pushing process of the transmission rod 41, the side strip 48 moves forward along the side groove 58. Therefore, the side strip 48 does not fill the entire side groove 58 at the beginning. The side strip 48 is closely matched with the side groove 58. When the side strip 48 moves forward, the side groove 58 is used as a guide groove. The lengths of the side strip 48 and the side groove 58 are substantially the same.

[0034] like Figure 2 , 3As shown in FIG. 4 , the transmission member 41 also has a push rod 43 located at the front end of the transmission member 41. The push rod 43 is connected to the front end of the side strip 48 and extends axially into the front compartment 51. The front compartment 51 is used to store the vascular clip 60. The push rod 43 acts on the clip 60 in the front compartment 51 and delivers the clip 60 to the opening of the clamp head 30. Figure 4 As shown, the front compartment 51 contains four clips 60. When the clips 60 are in the front compartment 51, they are in a flattened shape. When they leave the front compartment 51 and enter between the pair of clamp arms 31 and 32, the clips 60 are in a naturally opened shape, that is, as shown in FIG. Figure 4 The clip 60' is shown in its naturally open shape.

[0035] like Figure 3 As shown, the end of the side strip 48 of the transmission member 41 near the rear compartment 55 has a first clip, and the rear end of the push rod 43 is provided with a second clip, and the second clip and the first clip are mutually buckled, so that the push rod 43 is used as the axial extension of the transmission rod, and the push rod 43 acts on the clip 60 in the front compartment 51, and the clip 60 is sent to the clamp opening. Specifically, in the embodiment shown in the figure, the second clip and the first clip are concave and convex, the second clip is in an I-shaped shape at the rear end of the push rod 43, and the first clip is in a concave shape. Of course, in other embodiments, the second clip and the first clip are axially plugged in a buckling structure, or tooth meshing, or threaded connection. These connection structures are mainly to connect the push rod 43 and the transmission member 41 into one body, which can be connected and convenient for disassembly and assembly. For example, in the illustrated structure, the second clip and the first clip cannot be disassembled in the axial direction, but can be easily disassembled perpendicular to the axial direction. The top rod 43 is preferably in a sheet shape, and its length is substantially equal to that of the front compartment 51 .

[0036] like Figure 2 , 3 As shown in FIG. 4 , preferably, the driving member 42 includes a gear assembly, the rear end of the transmission member 41 has a tooth stripe 45, and the gear assembly has a gear 46 meshing with the tooth stripe 45, and the transmission member 41 is driven to move by the rotation of the gear 46. Specifically, as Figure 3 As shown, the gear 46 is mounted on a shaft 47, and a wheel handle 48 extends from one end of the gear 46 away from the tooth pattern. By pressing the wheel handle 48, the gear 46 drives the rack to move.

[0037] like Figure 3 and 4 As shown, specifically, the tube rod 20 is connected to a mounting tube 26 at the end near the push handle 10, and the mounting tube 25 is sleeved on one end of the transmission member 41 having a tooth stripe 45, and the mounting tube 25 is provided with a rack groove 26 at a position corresponding to the tooth stripe 45, and the tooth stripe of the gear 46 extends into the rack groove 26 and meshes with the tooth stripe 45.

[0038] like Figure 3 and 4 As shown, preferably, the mounting tube 25 is mounted on the push handle 10, and the mounting tube 25 is provided with fixing members 49 on both sides of the rack groove 26, and the gear 46 is clamped between the two fixing members 49 through a shaft rod 47. The rear end of the push-pull rod 12 away from the storage compartment 50 has a clamping portion 13 with a diameter larger than the main part of the push-pull rod 12, and the top of the push handle 10 is provided with a clamping groove 14, and the clamping portion 13 is clamped into the clamping groove 13. The clamping groove 13 is formed by digging a cylindrical groove downward from the top surface of the top of the push handle 10, and the clamping groove 13 has a slot facing the mounting tube 25, and the slot width is the same as the diameter of the main part of the push-pull rod 12, but smaller than the diameter of the clamping portion 13, and the cylindrical diameter of the clamping groove 13 is the same as the diameter of the clamping portion 13. Therefore, the clamping portion 13 of the push-pull rod 12 is inserted into the clamping groove 13 from the top surface of the push handle 10, and its axial disengagement is limited, and it can only be taken out from the top surface.

[0039] like Figure 4-6 As shown, the mounting tube 25 has a locking nut 27, and the locking nut 27 is penetrated with a screw 28 in a direction perpendicular to the axial direction of the mounting tube 25. When the transmission member 41 sends the clamp 60 to the opening of the clamps 31 and 32, the screw 28 is tightened so that the screw 28 is pressed against the outer surface of the transmission member to fix the transmission rod 41 and prevent the transmission rod 41 from being loosened. The screw 28 penetrates the pipe rod 20. The screw 28 is sleeved with a locking rod 281 for locking the screw 28.

[0040] like Figure 6 As shown, the mounting tube 25 is provided with an external thread at the front end near the locking nut 27, and an external nut 24 is sleeved on the external thread. The mounting tube 25 is dug with a step 251 at the inner wall corresponding to the position of the external thread. The rear end of the pipe rod 20 near the locking nut 27 is shrunken, and there is a connecting pipe section with a smaller pipe diameter. The end of the connecting pipe section abuts against the step 251. A sleeve 29 is provided on the outer wall of the connecting pipe section. The outer wall of the sleeve 29 has a convex ring, which is pressed by the external nut 24 and clamped to the external nut 24. When disassembling, first loosen the screw 28, take off the locking nut 27, and the pipe rod 20 can be pulled out, and the feeding device 40 and the storage compartment 50 can be cleaned. The disassembly and assembly are convenient, and the cleaning is convenient and quick. Then, loosen the external nut 24, the mounting tube 25 can be disassembled, the feeding device 40 and the storage compartment 50 can be separated, and the push-pull rod 12 can be taken out, which can be replaced or cleaned, which is also convenient, simple and quick to operate.

[0041] like Figure 7As shown, the front compartment 51 has an upper inner wall and a lower inner wall, and the upper inner wall and the lower inner wall are respectively provided with axially extending sliding ribs 512, and the upper and lower surfaces of the push rod 43 slide against the two sliding ribs 512. The front compartment 51 is provided with a guide notch 513 at the hatch side edge close to the opening of the clamps 31 and 32, so that the clamp 60 can slide out through the guide notches 513 on both sides when it escapes from the front compartment 51. Figure 3 As shown, the front end of the push rod 43 is provided with a corrugated groove 431, and the clip 60 is supported by the corrugated groove 431. The rear end of the clip 60 has a corrugated structure, and the corrugated groove 431 cooperates with the corrugated structure, so that the push rod 43 is tightly engaged with the clip 60 when the front compartment 51 moves forward, and the force transmission is smoother and labor-saving.

[0042] The inner side surfaces of the two clamp arms 31 and 32 facing each other are respectively provided with axially extending guide grooves 311 and 321, and the guide grooves 311 and 321 are communicated with the storage compartment 50, so that the clamp 60 enters the guide grooves 311 and 321 under the push of the transmission member 41. Specifically, the guide grooves 311 and 321 are axially communicated with the front compartment 50, that is, the guide grooves 311 and 321 are extended as the space in the front compartment 50, so that after the clamp 60 escapes from the front compartment 51, the two clamp arms of the clamp 60 smoothly enter the guide grooves 311 and 321, and when stopping bleeding of the blood vessel, the push-pull rod 12 drives the two clamp arms 31 and 32 to clamp, so that the clamp 60 clamps the blood vessel to stop bleeding.

[0043] It can be seen that the above-mentioned continuous clip applier 100 includes a feeding device 40 and a storage compartment 50. A plurality of clips 60 for blocking blood vessels can be pre-stored in the storage compartment 50, and then the feeding device 40 is cooperated to feed and move the clamp head 30 step by step. First, the clip 60 stored in the storage compartment 50 is pushed into the clamp head 30 by the transmission member 41, and the clip 60 is transported to the position. Then, the push-pull rod 12 acts on the front end of the storage compartment 50, and the clamp head 30 is clamped through the movable connection between the front end and the clamp head 30, so that the clip 60 sent to the clamp head 30 clamps the blood vessel. After clamping the blood vessel, the clamp head 30 needs to be loosened, and then the clamp head 30 is driven to open through the front end of the storage compartment 50 by the push-pull action of the push-pull rod 12, and then the clamp 60 of the next blood vessel is turned to clamp. Therefore, the above-mentioned continuous clip applicator can feed and clamp multiple or continuous hemostatic clips 60 at the same time, without the need for replacement, and without the need to remove the clip applicator 100 and reinstall the clip 60 outside the body. It can stop bleeding of multiple blood vessels in a timely, accurate and fast manner. The whole process is easy to operate, greatly saves operation time, improves operation efficiency, improves operation quality, reduces operation risks, greatly reduces patient pain, and allows for rapid postoperative recovery while maintaining high accuracy.

[0044] It should be noted that the present invention is not limited to the above-mentioned embodiments. Based on the creative spirit of the present invention, those skilled in the art may also make other changes. These changes made based on the creative spirit of the present invention should be included in the scope of protection required by the present invention.
