Description

Technical Field

[0001] The utility model relates to an obstetric forceps, in particular to an obstetric forceps with anti-pinching marks. Background Art

[0002] At present, forceps are an essential tool for obstetrics. When using them, first insert one blade of the forceps into the vagina and put it in place, then insert the other blade of the forceps into the vagina and put it in place, and then buckle the two blades together. At this time, the blades of the two blades clamp the fetal head, and the two handles fit together, and at the same time, grasp the two handles to pull the fetus outward.

[0003] However, the development of the fetus is not the same, so the size of the fetal head is also different. When using forceps, it is usually necessary to apply a clamping force to the shanks on the forceps so that the blades can firmly clamp the fetal head to prevent it from falling off during the traction process. When applying force, the medical staff directly grasps the two shanks and applies force to hold them tightly. However, the force applied by directly grasping the two shanks does not change, and there is no limit between the two shanks, causing the two shanks to move too much towards each other, and the two blades clamp the fetal head with too much force, which can easily cause red blood marks or bruises on both sides of the fetal head. Utility Model Content

[0004] The utility model aims to provide an anti-pinching forceps for obstetrics in view of the defects of the prior art.

[0005] In order to achieve the above-mentioned purpose of the utility model, the following technical solutions are adopted:

[0030] In order to enable those skilled in the art to better understand the technical solution in the present application, the technical solution of the present utility model will be clearly and completely described below in conjunction with the drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present application.

[0031] Embodiment 1:

[0032] like Figure 1-4As shown, an anti-pinching forceps includes a right forceps 1, a left forceps 2, a cushion 3 and a limiting force member 4. The right forceps 1 includes a right blade 11, a right shank 12 and a right handle 13. The right blade 11 is connected to one end of the right shank 12, and the other end of the right shank 12 is connected to the right handle 13. The left forceps 2 includes a left blade 21, a left shank 22 and a left handle 23. The left blade 21 is connected to one end of the left shank 22, and the other end of the left shank 22 is connected to the left handle 23. The left forceps 2 and the right forceps 1 are movably buckled. The cushion 3 is provided on the clamping ends of the right blade 11 and the left blade 21. One end of the limiting force member 4 is movably buckled on the right shank 12, and the other end is movably buckled on the left shank 22, so as to movably push the right shank 12 and the left shank 22 to move toward each other.

[0033] The soft pad 3 is wrapped on the right blade 11 and the left blade 21 respectively, and contacts with the fetus' head through the soft pad, so as to achieve soft contact with the fetus' head and avoid direct hard contact between the clamp blade and the baby. When clamping, the baby's head can be effectively protected.

[0034] like Figure 1 , 4 As shown, both the right blade 11 and the left blade 21 are provided with windows 100, which have a decompression effect and can facilitate the blades to fit the fetal head. The right blade 11 and the left blade can be elliptical structures.

[0035] The right blade 11 is connected to the right handle 13 via the right shank 12, and the left blade 21 is connected to the left handle 23 via the left shank 22, so as to increase the distance between the blade and the handle, which is beneficial for applying force to the two shanks.

[0036] like Figure 4 As shown, the right shank 12 is bent and connected to the right handle 13 in an arc. The left shank 22 is bent and connected to the left handle 23 in an arc.

[0037] like Figure 1 , 4 As shown, a plurality of arc grooves 200 are spaced apart along the length direction on the right handle 13 and the left handle 23. When the right pliers 1 and the left pliers 2 are buckled, the right handle 13 and the left handle 23 are correspondingly spliced ​​and closely connected. The plurality of arc grooves 200 can not only facilitate the hand to hold the right handle 13 and the left handle 23, but also play an anti-slip role.

[0038] like Figure 1 , 4 As shown, a buckle connection structure of the left pliers 1 and the right pliers 2 is provided. A limit convex plate 131 is additionally installed. A limit convex plate 131 is provided at the connection between the right handle 13 and the right shank 12, and the limit convex plate 131 and the right shank 12 form a limit groove 132, and the limit groove 132 is movably engaged with the left shank 22.

[0039] It should be noted that the right shank 12 and the left shank 22 have certain elasticity and can swing relative to the buckled connection between the left pliers 2 and the right pliers 1 when squeezed.

[0040] Embodiment 2:

[0041] Compared with Example 1, the difference lies in that the material structure of the soft cushion is provided.

[0042] One structure of the soft pad 3 can be a medical thermoplastic elastomer pad.

[0043] The material structure of the other end of the soft pad 3 is: another structure of the soft pad 1 can be a medical silicone pad.

[0044] Thermoplastic elastomers and silicone are both soft and can come into soft contact with the fetal head without slipping, making it easier for the two blades to clamp onto the fetal head.

[0045] Embodiment 3:

[0046] Compared with the first or second embodiment, the difference is that a structure of a position limiting force applying member is provided. Figure 2 , 3 As shown, the limiting force member 4 includes a support body 41, a support rod 44, a limiting sleeve 43, a support plate 49 and a pushing mechanism. The support body 41 is provided with a sinking groove 412, and an adjustment groove 42 is provided at the bottom of the sinking groove 412. One end of the support rod 44 is provided with an adjustment groove 42 and connected with a clamping plate 411, and the clamping plate 411 is embedded in the sinking groove 412. The limiting sleeve 43 is sleeved on the support rod 44 and is loosely connected with the support body 41. Support plates 49 are provided at both ends of the support body 41; each support plate 49 is installed with a pushing mechanism, and the pushing mechanism movably pushes the corresponding shank rod.

[0047] It should be noted that the width of the adjustment groove 42 is smaller than the width of the sink groove 412. The clamping plate is embedded in the sink groove 412, and its top surface is aligned with or slightly lower than the top surface of the support body 41. When the hand holds the limit force member, the clamping plate will not support the palm.

[0048] A connection structure between the limiting sleeve 43 and the support rod 44 is: the limiting sleeve 43 is threadedly connected to the support rod 44. The limiting sleeve 43 is sleeved on the support rod 44 to limit the distance of movement of the shank rod. When the limiting sleeve 43 is loosened, the support rod 44 can slide along the adjustment groove 42, and the clamping plate 411 can slide along the sink groove 412 to adjust the limiting sleeve 43, thereby limiting the movement distance of the shank rod. When the limiting sleeve 43 moves to the desired position, the limiting sleeve 43 is tightened, and the limiting sleeve 43 and the clamping plate 411 clamp the support body 41, so that the limiting sleeve 43, the support rod 44, the clamping plate 411 and the support body 41 are fixedly connected. It is understandable that the support rod 44 is kept on the support body under the action of the clamping plate 411 and the limiting sleeve 43, and will not fall out of the adjustment groove.

[0049] Working method:

[0050] Medical staff can learn the size of the fetus' head based on prenatal B-ultrasound data, and thus adjust the positions of the limiting sleeves 43 .

[0051] The support body 41 is buckled onto the forceps through the support plates 49 at both ends, that is, the support body 41 is buckled onto the left shank 22 and the right shank 12, and the left shank 22 and the right shank 12 are respectively corresponding to a pushing mechanism.

[0052] When the medical staff holds the limiting force member 4, the fingers overlap the pushing mechanism on one side of the limiting force member 4, and the thumb overlaps the pushing mechanism on the other side of the limiting force member 4. The fingers and thumbs apply force at the same time, and the two pushing mechanisms push the corresponding right shank rod 12 and left shank rod 12 to move accordingly. The right shank rod 12 and left shank rod 12 stop moving when they touch the limiting sleeve 43, and the right blade 11 and the left blade 21 firmly clamp the fetal head. Moreover, under the limiting action of the limiting sleeve 43, the right shank rod 12 and the left shank rod 12 can be effectively prevented from moving too far toward each other, so that the clamping force of the right blade 11 and the left blade 21 can be appropriate, and excessive clamping can be prevented, so as to better protect the fetal head.

[0053] Embodiment 4:

[0054] Compared with embodiment 3, the difference is that a structure of a pushing mechanism is provided. Figure 2 , 3 As shown, the pushing mechanism includes a movable plate 45 and a push rod 47. One end of the push rod 47 is connected to the grip plate 48, and the other end is penetrated by a support plate 49, and a spring 46 is connected to the movable plate 45, and one end of the spring 46 is connected to the support plate 49, and the other end is connected to the movable plate 45.

[0055] The push rod 47 can move relative to the support plate 49 to drive the movable plate 45 to move, so that the spring 46 undergoes elastic deformation.

[0056] Working method:

[0057] When a driving force is applied to the grip plate 48, the grip plate 48 drives the push rod 47 to move toward the insertion support plate 49, and the push rod 47 drives the movable plate 45 to move. When the movable plate 45 moves, the spring 46 is stretched, so that the spring 46 is elastically deformed and has elastic potential energy. The movable plate 45 is supported on the shank and drives the shank to swing. When the driving force on the grip plate 48 is released, the spring 46 pulls the movable plate 45 to elastically reset, so that the movable plate is separated from the shank in time. The shank is elastically reset under its own elastic action, that is, the right shank 12 and the left shank 12 are elastically reset, and the right blade 11 and the left blade 21 are released from clamping the fetal head.

[0058] Embodiment 5:

[0059] Compared with the third embodiment, the difference is that in order to facilitate the adjustment of the position of the limiting sleeve, a scale line 410 is provided. Figure 2 As shown, the scale lines 410 are distributed on the support body 41 along the length of the adjustment slot 42. The scale lines can facilitate the adjustment of the distance between the two limiting sleeves. When in use, medical staff can obtain the size of the fetal head based on the prenatal B-ultrasound data, and then adjust the distance between the two limiting sleeves, and the scale lines can facilitate the improvement of the accuracy of the adjustment distance between the two limiting sleeves.

[0060] According to the above embodiments, the working mode of the utility model is as follows:

[0061] The medical staff obtains the size of the fetal head based on the prenatal B-ultrasound data and adjusts the two limiting sleeves 43 on the limiting force applying member 4 to the required positions.

[0062] The medical staff inserts the right forceps 1 into the birth canal and places the right blade 11 on the right forceps 1 at the accurate position on one side of the fetal head. Then, the medical staff inserts the left forceps 2 into the birth canal and places the left blade 21 on the left forceps 2 at the accurate position on the other side of the fetal head. Then, the right handle 13 and the left handle 23 are movably buckled and spliced, and the right handle 13 and the left handle 23 are aligned and fit.

[0063] The medical staff buckles the limiting force-applying member 4 on the right shank 12 and the left shank 22 with one hand, and holds the spliced ​​right handle 13 and the left handle 23 with the other hand. The hand holding the limiting force-applying member 4 squeezes a pushing mechanism with the fingers and thumb respectively, that is, squeezes the grip plate 48, and the grip plate 48 pushes the push rod 47, and the push rod 47 pushes the movable plate 45. The movable plate 45 pushes the shank and pulls the spring 46 to produce elastic deformation. When the movable plate pushes the shank to swing and touch the limiting sleeve 43, the shank stops swinging. At this time, the right blade 11 and the left blade 21 firmly clamp the fetal head, and the limiting sleeve 43 limits the further swing of the shank. Therefore, even if the medical staff further increases the force on the limiting force-applying member during the traction process, the shank will not swing further, and the clamping force of the right blade 11 and the left blade 21 will not increase, which can help protect the fetal head.

[0064] The right blade 11 and the left blade 21 are provided with a cushion 3, and the right blade 11 and the left blade 21 are in soft contact with the fetal head through the cushion to prevent the right blade 11 and the left blade 21 from directly contacting the fetal head.

[0065] After the fetus is delivered, the medical staff can loosen the limiting force member 4, release the force applied to the gripping plate, and the spring 46 pulls the movable plate 45 to elastically reset, so that the movable plate 45 is separated from the shank in time, and the shank is reset under its own elastic action, and the right blade 11 is released from the left blade 21. The limiting force member 4 is removed from the forceps, and then the left forceps 2 and the right forceps 1 are separated and separated from the delivered baby, and the two sides of the baby's head are observed, and it is found that there is no red blood mark or bruise on the baby's head.

[0066] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
