Description

Technical Field

[0001] This utility model relates to a suture device with an adjustable angle beak for laparoscopic surgery, belonging to the field of medical device technology. Background Technology

[0002] Laparoscopic techniques are widely used in urological and andrological surgeries. The medical laparoscopic stapler relies on mechanical transmission principles; the handle drives a push rod to fire titanium alloy staples from the staple cartridge. After penetrating the tissue, the staples bend into a B-shape under the action of the anvil, achieving anastomosis and hemostasis.

[0003] The eagle beak feature is a curved, pointed structure at the tip of the laparoscopic suturing instrument, which can help safely pass through the intervascular and nerve spaces to avoid collateral damage. It can also be used for blunt dissection of tissue in deep surgical fields. The suturing instrument component with the eagle beak feature can precisely lift and gather the tissue to prevent tissue slippage and leakage during suturing, thereby improving the accuracy of alignment. It is suitable for narrow anatomical spaces, reduces the resistance to instrument insertion, assists in precise positioning, and significantly improves the safety and smoothness of minimally invasive operations.

[0004] Existing eagle beak designs are typically either one-piece molded or snap-on detachable, both of which present numerous inconveniences:

[0005] The one-piece molded eagle beak and anvil are machined as a whole, which is high in strength and low in cost, but the angle is fixed and the flexibility is low, limiting the applicable scenarios. Components with fixed eagle beak features can only be used for vascular closure. When performing large-area tissue suturing, the upward-curving eagle beak feature will press into the tissue and cause tissue damage. The snap-on detachable eagle beak is easy to install and remove and can be replaced, but it is easy to loosen after repeated use, and the separation and guiding functions weaken. More importantly, if it is accidentally left in the abdominal cavity during use, it will cause a major medical accident.

[0006] Therefore, there is an urgent need in this field to design a suturing instrument with an adjustable olecranon function to improve the many inconveniences of the existing olecranon features and thus cope with the suturing and hemostasis operation under laparoscopic surgery. Utility Model Content

[0007] The purpose of this invention is to provide a suture device with an adjustable angle olecranon for laparoscopic surgery, overcoming the aforementioned shortcomings in the prior art, and providing a device with outstanding practical functions, reasonable structural design, and convenient adjustment of the olecranon function.

[0008] To achieve the above-mentioned technical objectives and effects, this application provides the following technical solution: A laparoscopic suture device with an adjustable-angle auger includes a handle, an instrument rod, jaws, and a steering and propulsion mechanism. The jaws are connected to the handle via the instrument rod. The steering and propulsion mechanism is mounted on the handle and poweredly connected to the jaws via the instrument rod to control the jaws to swing within a preset angle. The jaws have replaceable staple cartridges and anvils that can be opened and closed. The jaws also include an auger hinged to the front end of the anvil. The anvil contains a control component that adjusts and fixes the tilt angle of the auger relative to the anvil.

[0009] Preferably, the front part of the anvil has a rotating groove, and the side wall of the anvil has a circular hole 1 that penetrates the anvil and the rotating groove. The beak has a circular hole 2 that matches the circular hole 1. The beak is rotated on the front part of the anvil through a rotating shaft that passes through the circular holes 1 and 2.

[0010] Furthermore, the rear part of the beak has a cylindrical connecting part, and the two circular holes coaxially pass through the cylindrical connecting part.

[0011] Furthermore, the control component includes an adjustment lever, which is slidably disposed in the anti-pin seat in a direction close to or away from the beak. The side of the adjustment lever facing the beak is the front side and has a protrusion. The outer wall of the cylindrical connecting part of the beak has a plurality of slots circumferentially distributed to fit the protrusion. When the protrusion is inserted into any of the slots, the rotation of the beak is restricted.

[0012] Furthermore, the control assembly also includes a locking spring. The anti-pin seat has a groove for the adjustment lever to slide. The rear side of the adjustment lever has a flat surface. One end of the locking spring is connected to the flat surface, and the other end is connected to the inner wall of the groove on the side away from the eagle's beak. The locking spring is always in a state where the adjustment lever tends to move towards the eagle's beak.

[0013] Furthermore, the adjusting lever has a vertical protrusion in the middle, and the bottom of the abutment seat has a sliding groove that communicates with the groove, and the vertical protrusion slides and engages with the sliding groove.

[0014] Furthermore, the end of the vertical protrusion facing away from the adjusting lever passes through a groove and protrudes from the bottom surface of the abutment seat.

[0015] The laparoscopic suture device with an adjustable-angle olecranon provided by this utility model has the following advantages: 1. The suture device of this utility model with adjustable angle eagle beak for laparoscopic surgery adopts a modular hinged structure with angle locking. Compared with the one-piece molded structure eagle beak, its advantages are in surgical adaptability and operational flexibility; it is more secure than the snap-on detachable type and will not fall off.

[0016] 2. The laparoscopic suture device of this invention has an adjustable olecranon, which can adjust the olecranon pitch angle in multiple positions during the operation to accurately fit the tissue morphology of different parts and angles. It is especially suitable for deep, narrow, and tricky laparoscopic surgical fields, and significantly reduces tissue damage caused by repeated instrument adjustments.

[0017] 3. The laparoscopic suture device of this invention with an adjustable angle eagle beak can be adapted to laparoscopic surgeries in multiple departments such as gastrointestinal, hepatobiliary, and urology, reducing the variety of instrument specifications and simplifying the configuration of the operating room.

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1-3 The laparoscopic suture device with an adjustable angle beak includes a handle 1, an instrument rod 2, jaws 3, and a steering and propulsion mechanism 4. The jaws 3 are connected to the handle 1 via the instrument rod 2. The steering and propulsion mechanism 4 is mounted on the handle 1 and is poweredly connected to the jaws 3 via the instrument rod 2 to control the jaws 3 to swing within a preset angle. The jaws 3 have a replaceable staple cartridge 31 and a staple seat 32 with an opening and closing mechanism. The above is the existing working structure of the laparoscopic suture device, which will not be described in detail.

[0022] Reference Figures 1-5 The jaws 3 also include a beak 33 hinged to the front end of the anvil 32, and an adjustment component 5 is installed inside the anvil 32 to adjust and control the tilt angle of the beak 33 relative to the anvil 32 and fix it.

[0023] The anvil 32 has a rotating groove 321 at the front. A circular hole 322 is provided on the side wall of the anvil 32, which passes through the anvil 32 and the rotating groove 321. A circular hole 3311 that matches the circular hole 322 is provided on the beak 33. The beak 33 is rotatably mounted on the front of the anvil 32 through a rotating shaft 34 that passes through the circular holes 322 and 3311.

[0024] In a further embodiment, the beak 33 has an integrally formed cylindrical connecting part 331 at the rear, and a second circular hole 3311 coaxially passes through the cylindrical connecting part 331.

[0025] Reference Figures 1-7 The control component 5 includes an adjustment lever 51, which is slidably disposed in the anti-pin seat 32 in a direction close to or away from the beak 33. The side of the adjustment lever 51 facing the beak 33 is the front side and has an integrally formed protrusion 511. Multiple slots 3312 that are adapted to be inserted into the protrusion 511 are distributed circumferentially on the outer wall of the cylindrical connecting part 331 of the beak 33. When the protrusion 511 is inserted into any slot 3312, the rotation of the beak 33 is restricted.

[0026] In a further embodiment, the control component 5 also includes a locking spring 52. The abutment seat 32 has a groove 323 for the adjustment lever 51 to slide. The rear side of the adjustment lever 51 has an integrally formed flat surface 512. One end of the locking spring 52 is connected to the flat surface 512, and the other end is connected to the inner wall of the groove 323 on the side away from the beak 33. The connection method includes, but is not limited to, welding or embedding, so that the locking spring 52 can stably extend and retract between the flat surface 512 and the inner wall of the groove 323. The locking spring 52 is always in a state where the adjustment lever 51 tends to move towards the beak 33.

[0027] In a further embodiment, the adjusting lever 51 has a vertical protrusion 513 in the middle, and the bottom of the anvil 32 has a groove 324 communicating with the recess 323. The vertical protrusion 513 and the groove 324 slide in cooperation. The end of the vertical protrusion 513 facing away from the adjusting lever 51 passes through the groove 324 and protrudes from the bottom surface of the anvil 32, so that the operator can control the sliding of the adjusting lever 51 by pushing the vertical protrusion 513 outside the jaws 3, thereby achieving the purpose of adjusting the angle of the beak 33.

[0028] The working principle of the laparoscopic suture device with an adjustable-angle eagle beak provided by this utility model is as follows: In use, the front protrusion 511 of the adjustment lever 51 is inserted into the slot 3312 at the corresponding angle of the beak 33. Under the pushing force of the locking spring 52, the insertion state is maintained, locking the beak 33. At this time, the beak 33 cannot rotate around the pivot 34.

[0029] In the adjusted state, the operator moves the vertical protrusion 513 in the middle of the adjusting lever 51 towards the locking spring 52 on the surface of the anvil 32, further compressing the locking spring 52. At this time, the front protrusion 511 of the adjusting lever 51 disengages from the slot 3312 of the beak 33, and the beak 33 can rotate around the pivot 34. The angle of the beak 33 can then be adjusted to an appropriate position. Releasing the vertical protrusion 513 in the middle of the adjusting lever 51, under the elastic force of the locking spring 52, the front protrusion 511 of the adjusting lever 51 inserts into the slot 3312 of the beak 33, locking the beak 33 in place.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit this utility model in any form or substance. It should be noted that those skilled in the art can make various improvements and additions without departing from this utility model, and these improvements and additions should also be considered within the protection scope of this utility model.
