Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a blunt separation forceps. Background Technology

[0002] Tissue dissection is a widely used surgical technique, primarily used to separate and lift tissues to facilitate further procedures. Tissue dissection includes sharp and blunt dissection. Sharp dissection involves using sharp scalpels and surgical scissors to perform precise layered dissection or separate adherent, firm scar tissue. Blunt dissection is often used for loose connective tissues, such as flattened muscles, interstitial spaces, tumor removal, and the removal of connective tissue or adhesions outside the cyst capsule. This method effectively prevents accidental damage to nerves and blood vessels while avoiding excessive tissue stretching and minimizing tissue dysfunction. Sharp dissection with a scalpel may sever muscle tissue, preventing its regeneration. Blunt dissection, using tools such as scalpel handles, hemostatic forceps, and fingers, aims to protect these tissues, similar to sharp dissection, but with a greater emphasis on protecting nerves and blood vessels, avoiding excessive tissue stretching, and minimizing tissue dysfunction.

[0003] Because blunt dissection often requires the use of ordinary surgical forceps, the forearm muscles are easily fatigued due to the constant abduction of the palm. In addition, the position of the forceps tip needs to be constantly monitored in order to protect nerves and blood vessels. Therefore, the use of traditional surgical forceps can be affected by uncomfortable operating postures and non-ergonomic design. Utility Model Content

[0004] The purpose of this invention is to provide a blunt dissection forceps that solves the problem of insufficient comfort and convenience in using traditional blunt dissection forceps. It has the advantages of ergonomic design, convenient force application, and comfortable operating posture.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A blunt-touch separation clamp includes two handles rotatably connected by a connecting shaft. One end of each handle is provided with a jaw, and the other end is provided with a grip. Each handle includes a gripping end and an operating end. The gripping end is connected to the gripping handle, and the operating end is connected to the jaw. The connecting shaft is located between the gripping end and the operating end. When the gripping ends are rotated to move closer together, the operating ends move further apart. An elastic element is installed between the gripping ends to provide a force that moves the gripping ends apart.

[0007] Preferably, the plane containing the pliers head and the two pliers handles forms an angle, which is a right angle or an obtuse angle.

[0008] Preferably, the end of the pliers head away from the pliers handle is provided with a sharp point.

[0009] Preferably, the length of the gripping end is greater than the length of the operating end.

[0010] Preferably, the pliers handle includes a first finger ring and a second finger ring respectively connected to two pliers handles, the first finger ring and the second finger ring having different inner diameters.

[0011] Preferably, a buffer pad is provided on the inner wall of the first ring and the second ring.

[0012] Preferably, the elastic element is a torsion spring, and a connecting buckle is provided on the inner wall of the gripping end, with the two ends of the torsion spring respectively mounted on the connecting buckle.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By designing the pliers handle and connecting shaft so that the operating end opens when the gripping end is tightened, the operator can better apply force to separate the tissue when the pliers head is inserted into soft tissue. In addition, an elastic element is provided between the gripping ends. When the operator releases the gripping end, the elastic element releases elastic potential energy to close the operating end, avoiding hand stiffness caused by prolonged gripping from affecting the pliers' exit from the working state.

[0015] 2. By setting the forceps tip to a sharp point, it can better penetrate between tissues, and the angle between the forceps tip and the handle can effectively avoid obstacles such as nerves, allowing for deep manipulation between tissues.

[0016] 3. By designing the handle with finger rings of different inner diameters, it meets the placement requirements of the thumb and the other four fingers. In addition, the inside of the finger rings is equipped with cushioning pads to reduce the pressure on the fingers and improve the comfort of the fingers during operation.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 As shown, a blunt-touch separating pliers includes two handles rotatably connected by a connecting shaft 4. One end of each handle has a jaw 3, and the other end has a grip. Each handle includes a gripping end 1 and an operating end 2. The gripping end 1 is connected to the gripping handle, and the operating end 2 is connected to the jaw 3. The connecting shaft 4 is located between the gripping end 1 and the operating end 2. When the gripping end 1 is rotated closer together, the operating end 2 moves away from each other. An elastic element 8 is installed between the gripping ends 1 to provide a force that pushes the gripping ends 1 away from each other. This separating pliers allows the two handles to rotate relative to each other via the connecting shaft 4. In use, the operator controls the gripping ends 1 to move closer together by gripping the handle with their fingers. Since the connecting shaft 4 is between the operating end 2 and the gripping end 1, the three form a lever structure. Furthermore, the operating end 2 and the gripping end 1 are located on the same side of the connecting shaft 4. According to the lever principle, when the gripping end 1 tilts downwards, the operating end 2 tilts upwards. Therefore, as... Figure 2 As shown, when the gripping ends 1 are controlled to move closer together, the operating ends 2 move further apart to open. At this time, the forceps head 3 follows the opening of the operating ends 2 to separate the tissue. This solution uses gripping force to achieve tissue separation, which is easier to apply force and less likely to cause fatigue compared to the traditional method of using the palm to spread outwards. The elastic element 8 between the gripping ends 1 helps the separating forceps return to their original position. Because the operator's fingers may become stiff from holding the gripping ends 1 for a long time, the elastic potential energy stored in the elastic element 8 is released after releasing the hand, separating the gripping ends 1 and closing the operating ends 2 again, allowing for further tissue separation without the operator needing to manually return the separating forceps to their original position, making the operation more convenient.

[0023] To avoid nerves and blood vessels in the tissue, such as Figure 3 As shown, the forceps head 3 forms an angle with the plane containing the two forceps handles. This angle can be either right or obtuse. The forceps head 3 is curved, its direction different from the handles, thus avoiding nerves and blood vessels. Even when the forceps head 3 is open, the operating end 2 of the handles does not obstruct the operator's view. A sharp point is provided at the end of the forceps head 3 furthest from the handles. This sharp point allows for easier insertion of the forceps head 3 into the tissue, facilitating tissue separation. The length of the gripping end 1 is greater than the length of the operating end 2. During operation, the gripping end 1 is on a longer lever arm. According to the lever principle, a longer lever arm requires less effort, thus reducing the force required by the operator when using the separation forceps.

[0024] like Figure 1 and Figure 2As shown, the forceps handle includes a first finger ring 5 and a second finger ring 6 connected to two handles respectively. The inner diameters of the first finger ring 5 and the second finger ring 6 are different. The forceps handle uses two finger rings with different inner diameters to allow for finger placement when the operator is using it. Generally, when the operator uses surgical forceps, the thumb controls one handle and the other four fingers control the other handle, which makes it easier to grip the forceps. The finger ring with the larger inner diameter can accommodate four fingers, while the other finger ring with the smaller inner diameter can accommodate the thumb. This design, which conforms to the user's habits, can effectively prevent the fingers from being squeezed. According to the operator's usage habits, if the operator is right-handed, the finger ring on the left handle is set to the smaller inner diameter; conversely, if the operator is left-handed, the finger ring on the right handle is set to the smaller inner diameter.

[0025] The aforementioned rings are used to accommodate the placement of fingers. Since the thickness of the ring material will also cause different degrees of pressure on the fingers, a buffer pad 7 is provided on the inner wall of the first ring 5 and the second ring 6. The buffer pad 7 can be made of a soft material, such as silicone or rubber, as a filler between the finger and the ring, which can reduce the pressure between the ring and the finger, making it more comfortable for the operator to use the separating forceps.

[0026] like Figure 1 and Figure 2 As shown, the elastic element 8 is a torsion spring, and a connecting buckle 9 is provided on the inner wall of the gripping end 1. The two ends of the torsion spring are respectively installed on the connecting buckle 9. There are various types of elastic elements 8, such as compression springs, torsion springs, and tension springs. In this solution, a torsion spring is chosen as the elastic element 8 because the two pliers handles rotate relative to each other. The torsion spring can store energy under torsional force, which is more in line with the movement state of the pliers handles. Compared with other types of springs, the energy storage is more stable. In addition, when installing the torsion spring, it can be hung on the connecting buckle 9 on the inner wall of the gripping end 1 through the two ends, which makes installation and disassembly more convenient and reduces production costs.
