Abstract
Description
Technical Field
[0001] This utility model belongs to the field of head-position delivery instruments, and in particular relates to a head-position delivery instrument. Background Technology
[0002] Forceps are a medical instrument used in gynecological obstetric delivery. In cases of low-lying dystocia, doctors will use forceps to assist in the operation. As long as the technique is correct and the forceps are placed in the right position, the baby can be delivered smoothly. When uterine contractions are weak, the second stage of labor is prolonged, or the mother has certain diseases that make it unsuitable to exert excessive force in the second stage of labor, or the fetus is hypoxic in utero, doctors recommend the use of forceps to assist in delivery.
[0003] In obstetric clinical practice, forceps are an important assisted delivery tool widely used in deliveries with difficult fetal head delivery. Traditional forceps designs typically consist of two halves, left and right, which need to be inserted separately into the birth canal on either side of the fetal head before use. During delivery, medical staff need to use certain techniques to merge the two halves of the forceps, insert them via a pivot, and lock them in place. This process is cumbersome and reduces work efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a head-position delivery device that can more easily merge two forceps, thereby improving its working efficiency to a certain extent.
[0005] The aforementioned head-position delivery device includes two clamp blades that can open and close together. Each clamp blade has a handle fixed to its tail. The two handles cross each other, and a slot is provided at the intersection of the two handles. The two handles are engaged in the slots and the two clamp blades are on the same horizontal plane. A positioning shaft is fixed to the bottom of one slot, and a positioning hole is provided at the bottom of the other slot. The positioning shaft is independently installed in the positioning hole and allows the two handles to swing relative to each other. A limiting plate is hinged to each handle to prevent the other handle from disengaging from the slot.
[0006] Furthermore, the inner surface of the clamp blade has a curved structure that matches the fetal head.
[0007] Furthermore, a cylindrical connector is fixed on the cleat corresponding to the slot, a positioning shaft is fixed at the center of one of the connectors, and a positioning hole is opened at the center of the other connector.
[0008] Furthermore, the connector and the clamp handle are integrally formed.
[0009] Furthermore, a sleeve is fixed inside the clamp handle, and a hinge post independent of it is installed inside the sleeve. The hinge end of the limiting plate is fixed to one end of the hinge post, and a limiting block is fixed to the other end of the hinge post to restrict its disengagement from the sleeve. Magnets are provided on the swing end of the limiting plate and the clamp handle to attract the two to each other. The limiting plate is located at the slot of the card slot.
[0010] Furthermore, a limiting buckle is fixed on the clamp handle at the swing end of the corresponding limiting plate to restrict the movement of the limiting plate along the groove direction of the slot. The limiting buckle has an "L" shaped structure.
[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes slots on the handles of the clamps. When merging, the other clamp handle is inserted into the slot, and then sealed by a limiting plate. This allows for the convenient merging of two-lobed delivery clamps consisting of two clamp blades and two handles, thereby improving work efficiency to a certain extent. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example
[0014] The head-position delivery device described in this embodiment, such as Figures 1 to 4As shown, the device includes two interlocking clamp blades 1. The inner surface of each clamp blade 1 has a curved structure that matches the fetal head. In use, the two clamp blades 1 are positioned on the left and right sides of the fetal head, respectively. Their curved structure allows for a better fit and gripping of the fetal head. Each clamp blade 1 has a handle 2 fixed to its tail. The two handles 2 intersect each other, and a slot is provided at the intersection of the two handles 2. The two handles 2 engage with each other in the slots, placing the two clamp blades 1 on the same horizontal plane. The openings of the two slots face each other and intersect, allowing the two handles 2 to enter each other's slots, ensuring that the two clamp blades 1 and the two handles 2 are on the same plane for easy operation by medical personnel.
[0015] One slot has a positioning shaft 4 fixed to its bottom, while the other slot has a positioning hole at its bottom. The positioning shaft 4 is independently inserted into the positioning hole, allowing the two clamp handles 2 to swing relative to each other. A cylindrical connector is fixed to each clamp handle 2 corresponding to its slot. The positioning shaft 4 is fixed at the center of one connector, and the positioning hole is located at the center of the other connector. The connector and clamp handle 2 are integrally formed. The connector increases the stability of the clamp handle 2's slot structure to a certain extent. Furthermore, the connector's fit against the slot wall also makes the clamp handles 2 more stable during their relative swinging. The positioning shaft 4 is independently inserted into the positioning hole, ensuring that the two clamp handles 2 swing around the positioning shaft 4.
[0016] Each clamp handle 2 is hinged with a limiting plate 3 to prevent the other clamp handle 2 from detaching from the slot. A sleeve 6 is fixed inside the clamp handle 2, and an independent hinge post is installed inside the sleeve 6. The hinge end of the limiting plate 3 is fixed to one end of the hinge post, and the other end of the hinge post is fixed with a limiting block to prevent it from detaching from the sleeve 6. A magnet 5 is provided on the swing end of the limiting plate 3 and the clamp handle 2 to magnetically attract them together. The limiting plate 3 is located at the opening of the slot. In use, the limiting plate 3 is used to confine the connector on the other clamp handle 2 within the slot, preventing it from falling out, and also limiting the up-and-down movement of the two connectors.
[0017] The limiting plate 3 can swing freely via the hinged column. When the other connector needs to enter the slot, the limiting plate 3 swings to open the slot on the other side, allowing the connector to enter. After the connector enters the slot, the swinging limiting plate 3 closes the slot opening. The swinging end of the limiting plate 3 is magnetically attracted to the clamp handle 2 by the magnet 5, locking the swinging end and preventing it from opening automatically, thus confining the other connector within the slot. During production, mounting slots are cut on the swinging end of the limiting plate 3 and the side wall of the clamp handle 2 to install the mutually magnetically attracted magnets 5 in the mounting slots.
[0018] A limiting buckle is fixed on the clamp handle 2 to the swing end of the corresponding limiting plate 3, restricting the movement of the limiting plate 3 along the groove opening direction. The limiting buckle has an "L" shaped structure. The limiting buckle locks the swing end of the limiting plate 3 to prevent the limiting plate 3 from moving along the groove opening direction, that is, to limit the shaking of the connector head along the groove opening direction.
[0019] In actual use, the two separate forceps blades 1 are inserted into the birth canal to the left and right sides of the fetal head. Then, the limiting plate 3 is rotated to open the slot, and the connector of the other forceps handle 2 is inserted into the slot. The positioning shaft 4 enters the positioning hole. Finally, the limiting plate 3 is moved to close the connector in the slot. This makes it relatively easy to merge the two forceps consisting of two forceps blades 1 and two forceps handles 2, and improves work efficiency to a certain extent. In addition, the swing end of the limiting plate 3 is magnetically attracted to the forceps handle 2 by the magnet 5, eliminating the need for additional locking steps and further improving work speed.
