Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a novel double-joint clamp for thoracoscopic surgery. Background Technology

[0002] In the field of minimally invasive thoracic surgery, thoracoscopic surgery has become an important clinical treatment method due to its advantages such as less trauma, faster recovery, and higher postoperative quality of life. With the continuous advancement of medical technology, single-port thoracoscopic surgery, with its smaller incision (about 3 cm) and less trauma, has gradually become dominant in major medical centers and has become the main form of thoracoscopic surgery.

[0003] There are various types of double-joint forceps for thoracoscopic surgery on the market, but they all use a single clamping head structure. In actual use, it is necessary to change the double-joint forceps for thoracoscopic surgery with different clamping heads according to the needs of the operation. This not only prolongs the operation time, but also requires the use of more instruments in a single operation, which increases the workload of the logistics department.

[0004] Therefore, a novel double-joint clamp for thoracoscopic surgery is proposed to address the above problems. Utility Model Content

[0005] (1) Technical problems solved

[0006] To address the shortcomings of existing technologies, this utility model provides a novel double-joint forceps for thoracoscopic surgery, which solves the problem that the clamping head structure of existing double-joint forceps for thoracoscopic surgery is relatively simple and requires frequent replacement during use.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a novel double-jointed forceps for thoracoscopic surgery, comprising a first forceps leg, a second forceps leg movably connected to the upper rear side of the first forceps leg, a first extension rod fixedly connected to the upper right side of the first forceps leg, a second extension rod movably connected to the upper right side of the second forceps leg, the second extension rod and the first extension rod being slidably connected in an interlocking manner, and a forceps mouth provided on the right side of both the first extension rod and the second extension rod;

[0009] The jaws include a main body, a flat jaw section on the right side of the main body, a concave jaw section and an oval through hole on one side of the flat jaw section, the oval through hole being located in the middle of the concave jaw section, and a crocodile tooth section on the left side of the main body.

[0010] Preferably, finger rings are fixedly connected to the lower parts of the first and second jaws on the sides that are far apart from each other, and biting blocks are fixedly connected to the middle parts of the sides that are close to each other. The first and second jaws are fixed to each other by two biting blocks.

[0012] Preferably, the biting block includes a fixing block, and a plurality of biting teeth are provided on one side of the fixing block, which are distributed at equal intervals. The fixing block is fixedly connected to the first jaw leg or the second jaw leg.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a novel double-joint clamp for thoracoscopic surgery, which has the following beneficial effects:

[0015] 1. This novel double-jointed forceps for thoracoscopic surgery features a flat clamping section, a concave clamping section, an oval orifice, and a crocodile-tooth section within the clamping jaws. During use, the flat clamping section allows for normal clamping operations, the concave clamping section can grasp hard tissues, and the oval orifice allows the grasped tissue to be exposed, facilitating the clamping of more hard tissues at once. The crocodile-tooth section facilitates the clamping of suture needles, making the clamping of suture needles more secure. The multi-functional clamping jaws reduce the need for frequent instrument changes during surgery, not only reducing surgical time but also alleviating the workload of hospital logistics departments in cleaning instruments.

[0016] 2. This novel double-jointed clamp for thoracoscopic surgery has bite blocks fixedly connected to the middle of the first and second clamp legs on the side close to each other. When it is necessary to clamp and close a blood vessel, the two clamp legs can be closed with a little force, so that the two bite blocks bite and limit each other, keeping the clamp closed and making it convenient for doctors to operate. When it is necessary to open the clamp, the two clamp legs can be slightly bent in opposite directions to separate the two bite blocks, and the clamp can be opened. It is very convenient to operate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-3 This utility model provides a technical solution: a novel double-jointed forceps for thoracoscopic surgery, including a first forceps leg 1, a second forceps leg 2 movably connected to the upper rear side of the first forceps leg 1, a first extension rod 5 fixedly connected to the upper right side of the first forceps leg 1, a second extension rod 6 movably connected to the upper right side of the second forceps leg 2, the second extension rod 6 and the first extension rod 5 being slidably connected in an interlocking manner, a forceps mouth 7 being provided on the right side of both the first extension rod 5 and the second extension rod 6, a finger ring 4 being fixedly connected to the lower, mutually distant sides of the first forceps leg 1 and the second forceps leg 2, and a biting block 3 being fixedly connected to the middle of the mutually close sides of the first forceps leg 1 and the second forceps leg 2, the first forceps leg 1 and the second forceps leg 2 being mutually fixed by two biting blocks 3.

[0025] Furthermore, such as Figure 1 and Figure 2 As shown, the jaws 7 include a main body 71. A flat jaw 72 is provided on the right side of the main body 71. A concave jaw 73 and an oval through hole 74 are provided on one side of the flat jaw 72. The oval through hole 74 is located in the middle of the concave jaw 73. A crocodile tooth 75 is provided on the left side of the main body 71. The main body 71 is fixedly connected to the first extension rod 5 or movably connected to the second extension rod 6. The crocodile tooth 75 is close to the first extension rod 5 and the second extension rod 6, while the flat jaw 72 is away from the first extension rod 5 and the second extension rod 6.

[0026] The above solution involves simultaneously providing a flat clamping part 72, a concave clamping part 73, an oval through-hole 74, and a crocodile tooth part 75 in the clamping mouth 7. When the device is in use, the multifunctional clamping mouth 7 allows doctors to avoid frequently changing instruments during surgical operations, which not only reduces surgical operation time but also reduces the workload of hospital logistics departments in cleaning instruments.

[0027] Furthermore, such as Figure 1 and Figure 3 As shown, the biting block 3 includes a fixing block 31, and a number of biting teeth 32 are provided on one side of the fixing block 31, which are distributed at equal intervals. The fixing block 31 is fixedly connected to the first jaw leg 1 or the second jaw leg 2.

[0028] The above solution involves placing a biting block 3 between each of the two clamp legs. When using a joint clamp to clamp a blood vessel, the two clamp legs can be fixed in place by the two biting blocks 3, making it convenient for the doctor to operate. When it is necessary to separate the two clamp legs, the two clamp legs can be slightly bent in the opposite direction to separate the two biting blocks 3, and the joint clamp can be opened.

[0029] Working principle: When using the forceps, when the doctor needs to clamp and close key parts such as blood vessels, he only needs to apply moderate force to close the two clamp legs, and the biting block 3 will automatically bite and lock, ensuring that the forceps remain in a stable closed state, which is convenient for the doctor to operate precisely. When it is necessary to release or readjust the forceps, simply gently bend the clamp legs in the opposite direction to separate the biting block 3, and the forceps can be easily opened. The whole operation process is smooth and labor-saving, which greatly improves the convenience and efficiency of surgical operation.

[0030] The jaws 7 incorporate four different clamping structures: the standard flat jaws 72 are used for routine clamping tasks, while the concave jaws 73 are specifically designed for hard tissues. Their unique shape allows for effective clamping and release of some tissue through the oval through-hole 74, facilitating the processing of more hard tissues at once. In addition, the introduction of the alligator tooth-like part 75 greatly improves the stability of needle clamping, making the suturing process more precise and efficient. This multi-functional design significantly reduces the frequency of instrument changes during surgery, shortening the operation time and reducing the burden on hospital logistics for cleaning and disinfecting surgical instruments.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
