Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a pair of tweezers with a shearing function. Background Art

[0002] Ophthalmology is a medical discipline that studies and treats eye diseases. It mainly focuses on the diagnosis, treatment and prevention of the eyeball, periocular tissues, visual system and their diseases. Ophthalmologists usually need to master knowledge of eye anatomy, physiology, disease diagnosis, treatment and surgical techniques. They use a range of tools and techniques to perform eye examinations, disease diagnosis and treatment, including vision tests, fundus examinations, corneal topography, corneal thickness measurements, pressure measurements, ultrasound examinations, laser surgery, etc.

[0003] When performing ocular nerve surgery, doctors often need to use tweezers and surgical scissors to cut away the diseased tissue. However, currently tweezers and surgical scissors are two independent instruments. After the doctor uses tweezers to clamp the diseased tissue, he needs to use his other hand to take the surgical scissors to remove the diseased tissue, which makes the operation process not smooth and increases the operation time. Utility Model Content

[0004] The utility model aims to provide a pair of tweezers with a shearing function which can improve the fluency of operation and reduce the operation time.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A pair of tweezers with a shearing function comprises a tweezer body, a mounting shell is installed on the outer surface of one side of the tweezer body, a slider is slidably installed inside the mounting shell along the length direction of the tweezer body, a push block is installed on the outer surface of the slider, an L-shaped plate is arranged on the lower side of the push block, a blade is arranged on the outer surface of the L-shaped plate near its end, a tension spring is arranged inside the mounting shell, and the two ends of the tension spring are respectively connected to the inner wall of the mounting shell and the outer surface of the slider.

[0007] It can be seen that after the diseased tissue is clamped by the forceps body, the push block can be directly pushed forward to drive the blade to remove the diseased tissue, thereby saving the time of taking the surgical scissors, making the entire operation process smoother, improving surgical efficiency, and reducing surgical time. In addition, through the setting of the tension spring, the blade can be pulled to always be in a position away from the front end of the forceps body, so that a safe distance is left between the blade and the front end of the forceps body, avoiding harm to the patient during the operation.

[0008] Furthermore, a bolt is vertically penetrated and threadedly connected inside the push block, and the bottom of the bolt is rotatably connected to the L-shaped plate. Limiting holes are provided on both sides of the push block, and limiting rods are installed on both sides of the upper surface of the L-shaped plate, and the limiting rods are arranged in the limiting holes.

[0009] Due to the joint action of the limiting rod and the limiting hole, the L-shaped plate can be limited. Therefore, when the bolt is rotated, the blade can be driven to rise and fall vertically. Therefore, the doctor can adjust the height of the blade according to the surgical situation to remove the diseased tissue.

[0010] Furthermore, a blocking block is installed on the inner wall of the mounting shell, and the blocking block is in contact with the sliding block via a tension spring.

[0011] Through the setting of the blocking block, when the blade is used to complete shearing, the tension of the tension spring is small, driving the slider and the blade to quickly reset. During the resetting process, the blocking block blocks the push block, so that the slider and the blade can quickly remain stable, avoiding reciprocating rebound and causing the blade to cause harm to the patient.

[0012] Furthermore, a mounting groove is provided on the outer surface of the L-shaped plate near its end, a mounting block is installed on the outer surface of the blade, and the mounting block is matched with the mounting groove, and a fastening screw is provided on the outer surface of the L-shaped plate.

[0013] When the blade needs to be replaced, the fastening screw can be unscrewed, and then the mounting block can be pulled out from the mounting slot, and then the mounting block on the replaced blade can be inserted into the mounting slot, and then the mounting block can be fixed with the fastening screw.

[0014] Furthermore, a silicone pad is provided on a side of the blocking block facing the sliding block.

[0015] By setting the silicone pad, it can play a buffering role when the tension spring pulls the slider to quickly reset and contact the blocking block, which not only prevents the slider from rebounding but also reduces the noise generated by hitting.

[0016] Furthermore, anti-slip stripes are provided on both sides of the outer surfaces of the tweezers body.

[0017] By setting the anti-slip stripes, the friction with the hand can be increased, thereby reducing the risk of hand slipping when using the tweezers body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The utility model is described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, a pair of tweezers with a shearing function comprises a tweezers body 100, a mounting shell 101 is installed on the outer surface of one side of the tweezers body 100, a slider 102 is slidably installed inside the mounting shell 101 along the length direction of the tweezers body 100, a push block 103 is installed on the outer surface of the slider 102, an L-shaped plate 104 is arranged on the lower side of the push block 103, a blade 105 is arranged on the outer surface of the L-shaped plate 104 near the end thereof, a tension spring 106 is arranged inside the mounting shell 101, and both ends of the tension spring 106 are respectively connected to the inner wall of the mounting shell 101 and the outer surface of the slider 102.

[0025] When in use, the doctor holds the forceps body 100 to clamp the patient's diseased tissue. After clamping, the doctor only needs to push the push block 103 forward. The push block 103 drives the slider 102 to slide horizontally inside the mounting shell 101 and stretches the tension spring 106, thereby driving the blade 105 to slide horizontally in the direction of the diseased tissue, thereby completing the purpose of resection. After resection, the push block 103 is directly released, and the stretched tension spring 106 contracts inward, thereby driving the blade 105 to quickly reset, so that the blade 105 is located away from the front end of the forceps body 100, leaving a sufficient safety distance to avoid injury to the patient during operation.

[0026] Specifically, a bolt 200 vertically penetrates and is threadedly connected to the inside of the push block 103, and the bottom of the bolt 200 is rotatably connected to the L-shaped plate 104. Limiting holes 201 are provided on both sides of the inside of the push block 103, and limiting rods 202 are installed on both sides of the upper surface of the L-shaped plate 104, and the limiting rods 202 are arranged in the limiting holes 201. Due to the joint action of the limiting rods 202 and the limiting holes 201, the L-shaped plate 104 can be limited. Therefore, when the bolt 200 is rotated, the blade 105 can be driven to rise and fall vertically. Therefore, the doctor can adjust the height of the blade 105 according to the surgical situation to remove the diseased tissue.

[0027] Specifically, a blocking block 300 is installed on the inner wall of the mounting shell 101, and the blocking block 300 is in contact with the slider 102 through the tension spring 106. Through the setting of the blocking block 300, after the shearing is completed using the blade 105, the tension of the tension spring 106 is small, driving the slider 102 and the blade 105 to quickly reset. During the resetting process, the blocking block 300 blocks the push block 103, so that the slider 102 and the blade 105 can quickly maintain stability, avoiding the reciprocating rebound that causes the blade 105 to cause harm to the patient.

[0028] Specifically, an installation groove 400 is provided on the outer surface of the L-shaped plate 104 near its end, and a mounting block 401 is installed on the outer surface of the blade 105, and the mounting block 401 is adapted to the mounting groove 400. A fastening screw 402 is provided on the outer surface of the L-shaped plate 104. When the blade 105 needs to be replaced, the fastening screw 402 can be unscrewed, and then the mounting block 401 can be pulled out from the mounting groove 400, and then the mounting block 401 on the replaced blade 105 can be inserted into the mounting groove 400, and then the mounting block 401 can be fixed with the fastening screw 402.

[0029] Specifically, a silicone pad 500 is provided on the side of the blocking block 300 facing the slider 102. Through the setting of the silicone pad 500, it can play a buffering role when the tension spring 106 pulls the slider 102 to quickly reset and contact the blocking block 300, which not only prevents the slider 102 from rebounding, but also reduces the noise generated by hitting.

[0030] Specifically, the outer surfaces of both sides of the tweezers body 100 are provided with anti-slip stripes. The provision of the anti-slip stripes can increase the friction with the hand, thereby reducing the risk of hand slipping during the use of the tweezers body 100.

[0031] The above is a detailed description of the utility model in combination with specific embodiments, and it cannot be determined that the specific implementation methods of the utility model are limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, making several equivalent substitutions or obvious modifications without departing from the concept of the utility model, and having the same performance or use, should be regarded as belonging to the patent protection scope of the utility model determined by the submitted claims.
