A kind of forceps

Abstract

The present invention relates to a medical tool, and in particular to a forceps, comprising a pair of forceps handles, wherein the inner side of any one of the pair of forceps handles or the opposite side of the pair of forceps handles are provided with a clamping sensing groove recessed toward the inner side of the forceps handles, and a finger is inserted into the clamping sensing groove to sense the clamping force of the forceps. When in use, one hand holds the forceps handle, and the index finger and ring finger of the other hand hook the pull handles on both sides of the forceps handle, and the middle finger is inserted into the clamping sensing forceps, so that the clamping force of the forceps can be sensed very conveniently through the clamping pressure of the two forceps handles of the middle finger. By allowing the user of the forceps handle to feel the clamping force of the forceps more personally through the clamping fingers, the damage and danger to the fetus caused by excessive clamping force can be greatly reduced.

Description

Technical Field

[0001] The invention relates to a medical tool, in particular to an obstetric forceps. Background Art

[0002] Forceps are a tool for assisting childbirth, including a handle, a forceps arm connected to one end of the handle, and a blade connected to the fetus on the arm. Figure 1 and Figure 2 . Forceps include single-leaf forceps and double-leaf forceps. Currently, double-leaf forceps are more widely used. When using them, one blade of the forceps is inserted into the vagina and placed in place, and then the other blade is inserted into the vagina and placed in place, and at the same time, it is closed with the previously inserted blade to form a hinged state, so as to clamp the fetal head, and then the forceps handle is grasped, and the two side handles on the forceps handle are used to pull the fetus.

[0003] However, if the clamping force is too large, it will have very serious consequences, such as causing damage to the fetal cheek, intracranial hemorrhage caused by clamping, etc., which seriously threatens the life and health of the fetus. Therefore, how to enable medical staff to conveniently and cost-effectively sense the size of the clamping pressure and reduce the damage to the fetus has become an issue worthy of attention. Summary of the invention

[0004] In view of the above problems, an object of the present invention is to provide forceps that can conveniently sense the pressure of clamping the fetus.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted in the present application is a pair of forceps, including a pair of forceps handles, and the inner side of any one of the pair of forceps handles or the opposite sides of the pair of forceps handles are provided with a clamping sensing groove recessed toward the inner side of the forceps handle, so that the fingers can sense the clamping force of the forceps after they are inserted into the clamping sensing groove.

[0006] After placing the forceps blades in place, when using them, hold the forceps handle with one hand, hook the pull handles on both sides of the forceps handle with the index finger and ring finger of the other hand, and insert the middle finger into the clamping sensing forceps. This makes it very convenient to sense the clamping force of the forceps through the clamping pressure of the two forceps handles with the middle finger.

[0007] By allowing the user of the forceps handle to feel the clamping force of the forceps more personally through the clamping fingers, the damage and danger to the fetus caused by excessive clamping force can be greatly reduced.

[0008] Of course, the usage here is not limited to using the middle finger for perception, and can also be different according to different operating habits and methods, that is, other fingers or parts of the human body can also be used for perception.

[0009] Furthermore, a pull handle protruding outward is provided on the outer side of the above-mentioned pliers handle, near one end of the pliers arm; in the straight line direction from the pliers arm to the pliers blade, the distance between the end of the above-mentioned clamping sensing groove near the pliers arm and the pliers arm is less than the distance between the above-mentioned pull handle and the pliers arm.

[0010] That is, the gripping sensing groove is closer to the front end of the forceps than the pulling handle, so that the user can place their fingers more comfortably when pulling the fetus by hand. For example, the index finger and ring finger are used to hook the pulling handle on both sides of the forceps handle, and the middle finger is inserted into the gripping sensing forceps, and the middle finger is placed more forward.

[0011] Furthermore, in the straight line direction from the clamp arm to the clamp blade, the distance between the end of the clamp sensing groove close to the clamp arm and the pull handle is greater than 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, or 10 cm. That is, a variety of specifications can be used to adapt to the position of human fingers.

[0012] Furthermore, the clamping sensing groove is a long strip groove extending along the length direction of the clamp handle.

[0013] A specific way is that the width of the clamping sensing groove gradually increases along the direction from the clamp handle to the clamp arm.

[0014] Another specific way is that the width of the clamping sensing groove gradually decreases along the direction from the clamp handle to the clamp arm.

[0015] In this way, the width of the clamping sensing groove can be adapted to the width of different people's fingers.

[0016] Furthermore, the maximum width of the clamping sensing groove is 3 cm to 5 cm. According to the width of human fingers, it is more appropriate to set the maximum width of the clamping sensing groove between 3 cm and 5 cm.

[0017] Furthermore, the minimum width of the clamping sensing groove is 1 cm.

[0018] Furthermore, a protective pad made of elastic material is arranged in the clamping sensing groove to protect the fingers of the user for sensing the clamping force.

[0019] Furthermore, the protective pad is detachably connected to the clamp handle to facilitate replacement, cleaning and disinfection. The protective pad can be disposable.

Additional aspects and advantages of the present invention will be partially given in the following description, partially become apparent from the following description, or be learned through the practice of the present invention.

[0031] The present invention is described clearly and completely below in conjunction with the accompanying drawings. A person skilled in the art will be able to implement the present invention based on these descriptions. Before describing the present invention in conjunction with the accompanying drawings, it should be particularly noted that:

[0032] The technical solutions and technical features provided in each part of the present invention, including the following description, may be combined with each other if there is no conflict.

[0033] In addition, the embodiments of the present invention involved in the following description are generally only embodiments of a part of the present invention, rather than all embodiments. Therefore, based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0034] About the terms and units in the present invention: The term "comprise" and any variation thereof in the description and claims of the present invention and related parts are intended to cover non-exclusive inclusions.

[0035] like Figure 3 and 4 , Embodiment 1:

[0036] The forceps include a pair of forceps handles 1, wherein the forceps handles 1 are connected to forceps arms 2, and the forceps arms 2 are connected to forceps blades 3. A clamping sensing groove 110 recessed toward the inner side of the forceps handle 1 is provided on the inner side of one of the pair of forceps handles 1, so that the fingers can sense the clamping force of the forceps after the fingers are inserted into the clamping sensing groove 110.

[0037] After the forceps blades 3 are placed in place, hold the forceps handle 1 with one hand, hook the pull handles 120 on both sides of the forceps handle 1 with the index finger and ring finger of the other hand, and insert the middle finger into the clamping sensing forceps. In this way, it is very convenient to sense the clamping force of the forceps through the clamping pressure of the two forceps handles 1 of the middle finger.

[0038] When not in use, after the two clamp handles 1 are closed, it is preferred that the fingers used to sense the clamping force cannot be inserted into the clamping sensing groove 110, or at least can only be inserted into the wider part of the clamping sensing groove 110.

[0039] like Figure 5 and 6 , Embodiment 2:

[0040] What is different from the first embodiment is that the pair of clamp handles 1 are both provided with a clamping sensing groove 110 recessed toward the inner side of the clamp handles 1 on the opposite sides thereof, that is, the clamping sensing groove 110 here is formed by merging two symmetrical grooves respectively provided on the two clamp handles 1, and the clamping sensing groove 110 is used for allowing the fingers to extend into the clamping sensing groove 110 after the two clamp handles 1 are closed so that the fingers can sense the clamping force of the forceps.

[0041] like Figure 7 , Embodiment 3:

[0042] On the basis of the first or second embodiment, a pad 4 made of elastic material is arranged in the clamping sensing groove 110, and the elastic material can be rubber, silicone, sponge or cotton cloth.

[0043] Preferably, the protective pad 4 is detachably connected to the clamp handle 1. The detachable connection here can be to put the protective pad 4 in the clamp sensing groove 110, or to wrap it in the position of the clamp sensing groove 110 corresponding to the clamp handle 1, or to stick it in the clamp sensing groove 110 by bonding.

[0044] like Figure 8The position of the clamping sensing groove 110 corresponding to the clamp handle 1, that is, the protective pad 4 is a cylindrical sleeve sleeved on the clamp handle 1, and a reserved hole 410 for the pull handle 120 to extend is set on the side of the cylindrical protective pad 4.

[0045] Embodiment 4:

[0046] On the basis of the first, second or third embodiment, the outer side of the clamp handle 1, near the end of the clamp arm 2, is provided with a pull handle 120 protruding outward; in the straight line direction from the clamp arm 2 to the clamp blade 3, (the straight line is Figure 3 The vertical symmetry line of the image is from the clamp arm 2 to the clamp blade 3), and the distance between the clamp arm 2 and the clamp arm 2 is less than the distance between the pull handle 120 and the clamp arm 2. In this way, the clamping sensing slot 110 of the present forceps can better conform to the distribution of fingers of the human body, such as hooking the pull handle 120 on both sides of the clamp handle 1 with the index finger and the ring finger, and inserting the middle finger into the clamping sensing clamp, and the middle finger is placed more forward.

[0047] Preferably, in the straight line direction from the clamp arm 2 to the clamp blade 3, the distance between the end of the clamp sensing groove 110 close to the clamp arm 2 and the pull handle 120 is greater than 1 cm.

[0048] Of course, there are many specifications, for example, the distance between the end of the clamping sensing groove 110 close to the clamp arm 2 and the above-mentioned pull handle 120 can be greater than 2cm, 3cm, 4cm, 5cm, 6cm, 7cm, 8cm, 9cm or 10cm.

[0049] In each of the above-mentioned embodiments, a preferred solution is that the clamping sensing groove 110 is a long strip groove extending along the length direction of the clamp handle 1.

[0050] A specific way is that the width of the clamping sensing groove 110 gradually increases along the direction from the clamp handle 1 to the clamp arm 2.

[0051] Another specific way is that the width of the clamping sensing groove 110 gradually decreases along the direction from the clamp handle 1 to the clamp arm 2.

[0052] This makes the clamping sensing groove 110 adapt to the width of different people's fingers. At the same time, during the process of the fingers sensing the clamping force, the pressure felt can be adjusted by sliding the fingers in the clamping sensing groove 110.

[0053] Because there is a certain correlation between the size of the hand and the width of the fingers, generally, the larger the hand, the wider the fingers, and vice versa, the smaller the hand, the narrower the fingers, so in this embodiment, it is preferred to adopt that the width of the clamp sensing groove 110 gradually increases along the direction from the clamp handle 1 to the clamp arm 2. That is, the larger the hand, the closer the middle finger is to the top of the clamp leaf 3, and the smaller the hand, the farther the middle finger is from the top of the clamp leaf 3. At the same time, it is also to prevent the finger used to sense pressure from involuntarily sliding to one side of the tail end of the clamp handle 1 due to the traction during the process of traction of the fetus, resulting in errors or failures in the finger sensing function, and to prevent the occurrence of unfavorable pressure on the traction and clamping of the fetus caused by the misalignment of the finger used for sensing during insertion and work.

[0054] Preferably, the maximum width of the clamping sensing groove 110 is 3 cm to 5 cm. According to the width of a human finger, it is more appropriate to set the maximum width of the clamping sensing groove 110 between 3 cm and 5 cm. Preferably, the minimum width of the clamping sensing groove 110 is 1 cm.

[0055] The above is a description of the relevant contents of the present invention. A person skilled in the art will be able to implement the present invention based on these descriptions. Based on the above contents of the present invention, all other embodiments obtained by a person skilled in the art without creative work shall fall within the scope of protection of the present invention.
