Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a blade-hidden umbilical cord scissors.
Background
Umbilical cord scissors are medical instruments commonly used in obstetrics and gynecology department, and at present, the following defects generally exist in the existing traditional umbilical cord scissors:
1. the blade of the umbilical cord scissors can not be hidden independently, so that the umbilical cord scissors are easy to injure infants and medical staff in the using process.
2. The traditional umbilical cord cutting process includes clamping, cutting, ligating and the like, the operation is complex, and the umbilical cord is cut off with certain danger and is easy to injure a newborn.
Disclosure of Invention
Aiming at the problems, the invention provides the umbilical cord scissors with the hidden blades, which can realize the automatic hiding of the blades, complete the processes of clamping, cutting, ligating and the like in one step and have simple operation.
The invention mainly adopts the following technical scheme: a hidden-blade umbilical cord scissors comprises an umbilical cord scissors main body and a housing; the umbilical cord scissors comprise two forceps bodies which are in X-shaped cross hinge joint, each forceps body comprises a handle and a forceps head, and the cross section of each forceps head is in an inverted trapezoid shape; the bottom surface of the tong head is provided with a blade;
the shell comprises an upper top surface, a lower bottom surface, a left side surface and a right side surface; the left side surface and the right side surface surround to form a cavity matched with the tong head; the shell is sleeved on the tong head, and a spring matched with the tong head and a slot matched with the blade are arranged on the lower bottom surface; the left side surface and the right side surface are respectively provided with an opening, a toothed umbilical cord clamp is arranged below the opening, and an elastic piece is arranged in the opening; the elastic piece comprises a fixing part and a herringbone part, the fixing part is fixedly connected with the left side surface and the right side surface respectively, and the tail end of the herringbone part is contacted with the dentate umbilical cord clamp;
under the condition that the spring is not subjected to external force, the blade edge surface is not higher than the toothed umbilical cord clamps, and under the condition that the spring is subjected to external force, the blade edge surface is higher than the toothed umbilical cord clamps;
the toothed umbilical cord clamp comprises a clamp ruler and a clamp wall, and a locking device is arranged at the tail end of the clamp wall.
The locking mechanism comprises a buckle arranged at one end part of one clamping wall and a clamping groove arranged at the other end part of the other clamping wall.
The handle is provided with a curved gripping part.
The blade can be dismantled and set up on the jaw.
Preferably, the cavity is a cuboid cavity, and the maximum width position of the trapezoid just contacts with the inner wall of the cuboid cavity. The inclination of the herringbone part of the elastic piece is matched with the inclination of the binding clip.
The toothed umbilical cord clamps may be secured by any means commonly used in the art, such as gluing, etc.
During the specific use, press the handle in the umbilical cord scissors main part, the binding clip of umbilical cord scissors main part draws close the closure gradually, the shell can be along with the umbilical cord scissors main part together closed, the cusp umbilical cord clamp of fixing at shell left surface and right flank can be close to the contact each other, the buckle of double-layered wall tip can with the draw-in groove block of another double-layered wall tip, thereby fix the shell, no longer remove along with the closure of umbilical cord scissors main part, however, because the spring that sets up in the cavity can be compressed, the umbilical cord scissors main part still can remove along the inside cavity of shell, make the blade expose the work of accomplishing the cutting umbilical cord from the fluting. When the blade finishes the process of cutting the umbilical cord, the clamp heads gradually get close to each other, when the clamp heads are in contact with the herringbone portion of the elastic piece, the herringbone portion is extruded from the opening hole under the action of external force, and then the tail end of the herringbone portion generates thrust on the clamping wall of the toothed umbilical cord clamp, so that the toothed umbilical cord clamp is separated from the shell. When the umbilical cord is cut, the handle is loosened, the spring automatically returns to hide the blade, the toothed umbilical cord clamps which are separated from the two sides of the shell cannot be loosened due to the action of the locking device, the toothed umbilical cord clamps can still be left at the mother and infant ends to clamp the cut umbilical cord, and the hemostatic effect is realized. The main body of the umbilical cord scissors and the shell can be withdrawn, and the main body of the umbilical cord scissors can also be withdrawn from the shell. The handle is provided with a bent gripping part, so that medical personnel can conveniently grip and operate the handle. The blade can be dismantled and set up on the binding clip, can only change the tool bit after the use, effectively avoids extravagant.
In summary, the invention has the following advantages:
(1) realize independently hiding of blade, avoid causing the injury to baby and medical personnel in the use.
(2) The processes of clamping, cutting, ligating and the like are completed in one step, and the operation is simple;
(3) the dentate umbilical cord clamps can automatically leave the shell in the umbilical cord cutting process, thereby avoiding the process that medical personnel additionally peel off the umbilical cord clamps from the umbilical cord scissors, and having simple structure and more convenient use.
