Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a pair of scissors for obstetrics. Background Technology
[0002] Obstetric scissors are indispensable tools in obstetric and gynecological surgeries, mainly used for cutting the umbilical cord, cutting perineal tissue, and incising the amniotic sac. These scissors are usually made of stainless steel. Existing scissors require the doctor to manually open them during use. By adding spring clips or other elastic components, the scissors can be kept open, allowing for easy cutting with a simple press. However, the spring clips prevent them from being stored properly, keeping them in the open position.
[0003] A search revealed Chinese patent application number 202121091653.7, which discloses a pair of scissors for obstetrics. The scissors include a main handle, mounting holes, positioning holes, a spring clip, and a secondary handle. A quick-fixing device is installed inside the upper left of the main handle, and a locking mechanism is inserted into a slot. This causes a second telescopic rod to move the locking mechanism downwards, engaging it with the top left end of the locking mechanism, thus quickly fixing the secondary handle. This device is convenient to use and simple to operate, effectively improving surgical efficiency. The locking mechanism, located inside the left of the secondary handle, allows the third telescopic rod and second spring to extend when the push rod is released, causing the hook to insert into the slot and engage with the locking mechanism, thus securing the secondary handle and preventing inconvenience.
[0004] While the aforementioned patent allows for the storage of the knife handle, it secures the handle by connecting it to a retractable hook and a locking mechanism. However, during use, the handle needs to be repeatedly pressed to cut. This can easily cause the hook and locking mechanism to connect together before the cutting is completed when the handle is pressed to the bottom. In this case, the handle needs to be unlocked again before cutting can be done again. Repeated unlocking greatly reduces cutting efficiency and affects normal cutting operations.
[0005] Therefore, there is an urgent need for obstetric scissors to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to solve the problem in the prior art that the hook and the clip are easily connected when pressed, requiring unlocking before reuse and reducing cutting efficiency. Therefore, this invention proposes a pair of scissors for obstetrics.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A pair of obstetric scissors includes a first scissor body and a second scissor body rotatably connected by a rotating component. Both the first and second scissor bodies consist of scissor arms with blades and handles. A spring is also provided between the first and second scissor bodies. A handle assembly is installed at the handle position of both the first and second scissor bodies. A limiting hole is formed at the tail end of the handle of both the first and second scissor bodies. A limiting component is movably installed in the limiting hole of the second scissor body. The limiting component includes a movable post passing through the limiting hole. A first limiting baffle is installed at one end of the movable post, and a second limiting baffle is installed at the other end of the movable post. A placement groove for placing the second limiting baffle is formed on the upper surface of the handle of the second scissor body facing the first scissor body at the limiting hole.
[0009] As a preferred technical solution of this application, the ends of the scissor arms of both the first and second scissor blades are rounded.
[0010] As a preferred technical solution of this application, the spring includes a collar sleeved on the rotating member, and spring rods are respectively provided at both ends of the collar.
[0011] As a preferred technical solution of this application, a placement slot for placing the collar and the spring rod is provided on the opposite side of the first shear and the second shear.
[0012] As a preferred technical solution of this application, the rotating component includes a rotating sleeve and a screw threadedly connected to the rotating sleeve, and both the rotating sleeve and the screw have baffles at their outer ends.
[0013] As a preferred technical solution of this application, the handle kit includes an anti-slip handle, one end of which is equipped with a post that is inserted into the corresponding opening of the handle.
[0014] As a preferred technical solution of this application, a stop bar is installed at the other end of the anti-slip handle.
[0015] As a preferred technical solution of this application, a mounting plate is installed at the bottom of the stop bar, and fastening screws are provided on the mounting plate.
[0016] As a preferred technical solution of this application, the first limiting baffle is connected to the second shear body by a spring.
[0017] Compared with the prior art, this utility model provides a pair of scissors for obstetrics, which has the following beneficial effects:
[0018] 1. The obstetric scissors, through the setting of a limiting component, achieve the following: when the limiting hole on the first scissor body is locked onto the movable post inside the second limiting baffle, the scissors are kept in a closed state. During use, under the action of elasticity, the second limiting baffle is moved away from the first scissor body, which will not cause false limiting of the first scissor body when pressed. This solves the problem in the prior art that false limiting occurs when pressed to the bottom, which requires unlocking before it can be used again.
[0019] 2. The obstetric scissors, by setting a rotating component including a rotating sleeve and a screw threadedly connected to the rotating sleeve, make it easy to disassemble the first and second shears during use, thus solving the problem that the scissors in the prior art are inconvenient to disassemble for cleaning, maintenance and disinfection after use;
[0020] 3. The obstetric scissors have placement slots on the opposite sides of the first and second shear blades for placing the collar and spring rod. This allows the spring to be placed between the first and second shear blades, maintaining its stability during use and preventing it from falling off. This solves the problem in the prior art where the spring is unstable during connection and is prone to falling off during use. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example
[0031] Reference Figures 1-7 A pair of scissors for obstetrics includes a first scissor body 1 and a second scissor body 2 rotatably connected by a rotating component 3. Both the first scissor body 1 and the second scissor body 2 consist of scissor arms with blades and handles. When cutting, the material is cut by pressing the handle and the scissor arms. The ends of the scissor arms of the first scissor body 1 and the second scissor body 2 are rounded to prevent the sharp ends from accidentally touching the patient and causing wounds when used in obstetrics.
[0032] Reference Figure 3 and Figure 4 Furthermore, a spring piece 6 is provided between the first shear body 1 and the second shear body 2. Under the elastic action of the spring piece 6, the angle between the first shear body 1 and the second shear body 2 increases. During use, only pressing is required for cutting, which is labor-saving and convenient. The spring piece 6 includes a collar 601 sleeved on the rotating part 3. The two ends of the collar 601 are respectively provided with spring rods 602. The opposing surfaces of the first shear body 1 and the second shear body 2 are provided with placement slots for placing the collar 601 and the spring rods 602. Placing the spring piece 6 between the first shear body 1 and the second shear body 2 can maintain the stability of the spring piece 6 during use and prevent it from falling off. At the same time, the concealed placement reduces its space occupation.
[0033] Reference Figure 5 Furthermore, the rotating component 3 includes a rotating sleeve 301 and a screw 302 threadedly connected to the rotating sleeve 301. Both the outer ends of the rotating sleeve 301 and the screw 302 are provided with baffles. By removing the screw 302 during disassembly, the first shear body 1 and the second shear body 2 can be separated, which facilitates cleaning, maintenance and disinfection of the first shear body 1 and the second shear body 2.
[0034] ReferenceFigure 2 and Figure 6 Furthermore, both the first scissor body 1 and the second scissor body 2 are equipped with handle kits 4. The handle kits 4 provide a more comfortable grip and increase friction to prevent slippage. The handle kit 4 includes an anti-slip handle 403, one end of which is fitted with a post 404 that inserts into the corresponding opening on the handle. The other end of the anti-slip handle 403 is fitted with a stop bar 401 to improve stability when gripping. A mounting plate 405 is fitted at the bottom of the stop bar 401, and a fastening screw 402 is provided on the mounting plate 405 to fix the handle kit 4 to the handle during installation. The handle kit 4 is easy to disassemble and replace. During use, the anti-slip protrusions on the anti-slip handle 403 effectively increase friction when gripping, while the stop bar 401 also improves stability when gripping.
[0035] Reference Figure 1 , Figure 4 and Figure 7 Furthermore, both the first shear body 1 and the second shear body 2 have limit holes 7 at their handle ends. A limit component 5 is movably installed in the limit hole 7 on the second shear body 2. The limit component 5 includes a movable post 503 that passes through the limit hole 7. A first limit baffle 501 is installed at one end of the movable post 503, and a second limit baffle 504 is installed at the other end of the movable post 503. The upper surface of the handle on the second shear body 2 facing the first shear body 1 has a placement groove at the limit hole 7 for placing the second limit baffle 504. When the restriction is released, the second limit baffle 504 is stored in the placement groove, so that the movement of the first shear body 1 is not restricted during cutting, making it more convenient to use. The first limit baffle 501 is elastically connected to the second shear body 2 by a spring 502. After the restriction is released, the second limit baffle 504 is placed in the placement groove under the action of the spring 502, preventing the second limit baffle 504 from sliding out and affecting the cutting action.
[0036] Specifically, when the scissors intended for obstetrics are in operation / use: the second scissor body 2 is fitted onto the rotating sleeve 301, and then the spring clip 6 is installed. Next, the first scissor body 1 is installed onto the rotating sleeve 301. While the first scissor body 1 is installed, the spring clip 6 is engaged with the corresponding slots of the first scissor body 1 and the second scissor body 2, and then secured with the screw 302. After connection, when storing, the handles of the first scissor body 1 and the second scissor body 2 are brought close together, ensuring that the limiting holes 7 on them are aligned. Then press the limiting member 5 so that one end of the second limiting baffle 504 on the limiting member 5 is inserted into the limiting hole 7 on the first shear body 1. Under the action of the spring piece 6, the limiting hole 7 is locked on the movable column 503 inside the second limiting baffle 504, and the storage is completed. When it is needed, the limiting hole 7 is aligned by holding the handles of the first shear body 1 and the second shear body 2. The second limiting baffle 504 is retracted under the elastic force of the spring 502, the restriction is released, and then the shearing operation is carried out.
[0037] 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.
