Description

Technical Field

[0001] This utility model relates to the field of laryngeal forceps technology, and in particular to a universally flexible laryngeal forceps for microsurgery. Background Technology

[0002] Laryngeal forceps are medical forceps inserted into the larynx via microscopic imaging. Due to the unique structure of the mouth and larynx, traditional laryngeal forceps present certain inconveniences during use. Their inflexible, straight shape increases the difficulty for the operator to smoothly insert the forceps into the patient's larynx, especially when viewing the microscopic image, thus hindering the successful execution of the surgery. Therefore, we propose a omnidirectional, flexible laryngeal forceps for microsurgery. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a universally flexible laryngeal clamp for microsurgery.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A omnidirectional flexible laryngeal forceps for microsurgery includes a bent rod and a connecting rod welded together. The interior of the bent rod and the connecting rod are hollow, and the inner surface of the bent rod has several spaced annular grooves.

[0006] The bending rod has a pliers head welded to its front end, and the connecting rod has a handle head tube welded to its rear end. The handle head tube has a placement cavity inside, and the front end of the placement cavity is connected to the rear end of the connecting rod. The handle head tube has a rinsing hole at its rear end.

[0007] A piston rod is installed at the front end of the placement cavity. A traction steel rope is connected between the front end of the piston rod and the movable jaw of the clamp head. The traction steel rope passes through the bent rod and the connecting rod.

[0008] A push spring is installed at the rear end of the placement cavity, and the front end of the push spring contacts the rear end of the piston rod.

[0009] The piston rod has uniformly distributed through grooves between its two ends on its outer surface, and a handle assembly is provided at the front end of the handle head tube.

[0010] Preferably, the bending rod is a bend-resistant metal tube, and the outer surfaces of the bending rod and the connecting rod are smooth.

[0011] Preferably, the inside of the pliers head and the bending rod are in a connected state.

[0012] Preferably, when the piston rod is located at the front of the placement cavity, there is a gap between the front end face of the piston rod and the front end of the placement cavity.

[0013] Preferably, there is a gap between the traction steel rope and the inner surface of the bending rod and the connecting rod.

[0014] Preferably, the handle assembly includes a fixed handle and a movable handle. The fixed handle is located in front of the movable handle, and the upper parts of the fixed handle and the movable handle are rotatably connected by a pin. The upper end of the fixed handle is welded to the handle head tube, and the upper end of the movable handle is provided with a drive head.

[0015] The handle head tube has a through hole corresponding to the drive head on its tube wall, and the piston rod has an insertion interface corresponding to the through hole. The upper end of the drive head extends into the insertion interface through the through hole.

[0016] This invention proposes a universally flexible laryngeal forceps for microsurgery, which has the following advantages: During application, the bending rod can be bent, and the presence of the annular groove makes bending the rod simple and effortless, while also increasing the number of bends and extending its service life. Based on the observed microscopic images, the operator can use experience to bend the rod to the appropriate arc and angle, thereby reducing the difficulty of smoothly inserting the forceps into the patient's larynx and facilitating the smooth progress of the surgery.

[0024] Reference Figure 1-4 A universal bendable laryngeal forceps for microsurgery includes a bending rod 2 and a connecting rod 3 welded together. Both the bending rod 2 and the connecting rod 3 are hollow inside. The inner surface of the bending rod 2 has several spaced annular grooves 201. The bending rod 2 is specifically a bend-resistant metal tube. The outer surfaces of the bending rod 2 and the connecting rod 3 are smooth, allowing the bending rod 2 to be bent. The presence of the annular grooves 201 makes bending simple and can also increase the number of bends and extend the bending life.

[0025] A pliers head 1 is welded to the front end of the bent rod 2, and the inside of the pliers head 1 is connected to the bent rod 2.

[0026] A handle head tube 4 is welded to the rear end of the connecting rod 3. The handle head tube 4 has a placement cavity 401 inside. The front end of the placement cavity 401 is connected to the rear end of the connecting rod 3. A flushing hole 403 is opened at the rear end of the handle head tube 4.

[0027] A piston rod 402 is installed at the front end of the placement cavity 401. When the piston rod 402 is located at the front of the placement cavity 401, there is a gap between the front end face of the piston rod 402 and the front end of the placement cavity 401.

[0028] The front end of the piston rod 402 is connected to the movable jaw of the jaw head 1 by a traction steel rope 7. The traction steel rope 7 passes through the bent rod 2 and the connecting rod 3. There is a gap between the traction steel rope 7 and the inner surface of the bent rod 2 and the connecting rod 3.

[0029] A push spring 8 is installed at the rear end of the placement cavity 401. The front end of the push spring 8 is in contact with the rear end of the piston column 402. When the push spring 8 is not under force, the piston column 402 is in front of the placement cavity 401.

[0030] A uniformly distributed through groove 4021 is provided between the two ends of the outer surface of the piston column 402. A handle assembly is provided at the front end of the handle head tube 4. The handle assembly includes a fixed handle 5 and a moving handle 6. The fixed handle 5 is placed in front of the moving handle 6, and the fixed handle 5 and the moving handle 6 are rotatably connected by a pin on the upper side that is close to each other. The upper end of the fixed handle 5 is welded to the handle head tube 4, and a drive head 601 is provided at the upper end of the moving handle 6.

[0031] A through hole 404 is provided on the tube wall of the handle head tube 4 corresponding to the drive head 601, and an insertion interface 4022 is provided on the piston column 402 corresponding to the through hole 404. The upper end of the drive head 601 extends into the insertion interface 4022 through the through hole 404.

[0032] Therefore, during use, based on the observed microscopic images, the operator can perform omnidirectional bending of the bending rod 2 according to the corresponding arc and angle, thereby reducing the difficulty for the operator to smoothly insert the laryngeal forceps into the patient's larynx. After being inserted into the target position, the operator's hands manipulate the lower part of the fixed handle 5 and the moving handle 6 to move closer together. At this time, under the drive of the drive head 601, the piston column 402 moves towards the rear of the placement cavity 401 and the push spring 8 is compressed. That is, the traction steel rope 7 pulls the movable jaw of the forceps head 1 to move towards the fixed jaw, thereby achieving the clamping of the object being clamped. The operation is simple and convenient, which helps the operation proceed smoothly.

[0033] Meanwhile, during the cleaning and disinfection process after use, cleaning and disinfecting solutions can be filled into the entire laryngeal forceps through the rinsing hole 403. When the filled cleaning and disinfecting solutions enter the rear of the placement chamber 401 through the rinsing hole 403, they can enter the front of the placement chamber 401 through the through groove 4021 on the piston column 402 and the gap between the piston column 402 and the handle head tube 4. Then, the cleaning and disinfecting solutions in the front of the placement chamber 401 can be discharged through the connecting rod 3, the bending rod 2 and finally through the forceps head 1, thus achieving contact with every surface inside the laryngeal forceps, making the cleaning and disinfection of the inside of the laryngeal forceps simple, convenient and easy to operate.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
