Description
Technical Field
[0001] The utility model belongs to the technical field of puncture sheaths, and particularly relates to a novel puncture sheath. Background Art
[0002] An endoscope is a detection instrument integrating traditional optics, ergonomics, precision machinery, modern electronics, mathematics, software, etc. With the rapid development of minimally invasive medicine, the traditional open surgery method has gradually been replaced by the endoscope surgery method. The endoscope surgery method has the advantages of small incision, high safety, fast recovery, and little harm to patients. In endoscope surgery, as an essential medical device, the main function of the puncture sheath is to serve as an insertion channel for instruments such as endoscopes and surgical forceps. Most of the existing puncture sheaths are composed of two main parts: a puncture needle tube and a puncture stylet. And to make it convenient for medical staff to operate, one end of the puncture stylet in contact with the palm is usually dome-shaped.
[0003] However, during the endoscope surgery process, inevitably, the patient's tissue fluid or blood will stick to the endoscope lens, which will affect the surgical field of view. The general treatment method is to withdraw the endoscope from the patient's body, wipe it clean, and then continue the surgery. This method of dealing with lens contamination is not only cumbersome but also prone to cause additional surgical risks. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a novel puncture sheath is proposed. Its advantages are as follows: When cleaning the contaminated lens, there is no need to pull out the lens from the patient's body, which improves the work efficiency of medical staff and reduces additional surgical risks.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A novel puncture sheath, including a puncture stylet and a puncture needle tube. The puncture stylet is inserted into the puncture needle tube. A cleaning mechanism is arranged on one side of the puncture needle tube, and a holding mechanism is arranged on the top of the puncture stylet;
[0007] An activity groove is opened at the bottom of the outer wall of the puncture needle tube. A baffle is hinged to the inner wall of the top of the activity groove. A medical dust-free cloth is fixedly connected to one side of the baffle close to the puncture stylet. The medical dust-free cloth is in contact with the surface of the puncture stylet. The medical dust-free cloth is soaked with iodophor. An air outlet valve is fixedly connected to the top of the outer wall of one side of the puncture needle tube. The air outlet valve is communicated with the puncture needle tube.
[0008] Through the above technical solution: during use, insert the puncture core into the puncture needle tube, and then the operation can be carried out. The staff can hold the stopper with their hand, so that the puncture core can move up and down in the puncture needle tube, which can ensure that the hand is more stable during the puncture operation and reduce the surgical risk. As the puncture needle tube moves, under the pulling force of the spring, the medical dust-free cloth impregnated with iodophor can clean the surface of the puncture core. Therefore, when cleaning the contaminated lens, there is no need to pull out the lens from the patient's body, which improves the work efficiency of medical staff and reduces unnecessary surgical risks.
[0009] The utility model is further arranged such that a spring is fixedly connected to the inner wall of the top of the movable groove, and the spring is fixedly connected to the baffle.
[0010] Through the above technical solution: the setting of the spring can apply force to the baffle, so that when the puncture core moves, the medical dust-free cloth can clean it.
[0011] The utility model is further arranged such that the outer surface of the baffle is flush with the outer wall surface of the puncture needle tube.
[0012] Through the above technical solution: it can avoid the uneven feeling between the baffle and the puncture needle tube, and avoid causing unnecessary additional harm to the patient.
[0013] The utility model is further arranged such that when the spring contracts, the baffle makes a counterclockwise movement perpendicular to the hinge at the hinge.
[0014] Through the above technical solution: it can make the medical dust-free cloth fit with the puncture needle tube, and the staff can automatically clean the puncture needle tube by moving the puncture needle tube.
[0015] The utility model is further arranged such that the holding mechanism includes a stopper fixedly connected to one side of the top of the puncture core.
[0016] Through the above technical solution: the setting of the stopper can facilitate the staff to operate the puncture core, so as to reduce the interference probability between the instruments during the operation.
[0017] The utility model is further arranged such that the position where the stopper contacts the tiger's mouth of the hand is in an arc-shaped structure.
[0018] Through the above technical solution: the arc-shaped structure design conforms to ergonomics, makes the puncture core receive more uniform force, and makes the puncture operation more stable.
[0019] The utility model is further arranged such that the outer wall surface of the puncture needle tube is provided with grooves linearly arrayed in the vertical direction, and the grooves are in an annular structure.
[0020] Through the above technical solution: the setting of the groove can increase the surface roughness of the puncture needle tube, and can prevent it from slipping off the hands of the staff.
[0021] The beneficial effects of the present utility model are as follows:
[0022] 1. For this new puncture sheath, by inserting the puncture core into the puncture needle tube, the operation can be carried out. The staff can hold the stopper with their hands, so that the puncture core can move up and down in the puncture needle tube, which can ensure that the hand is more stable during the puncture operation and reduce the surgical risk. As the puncture needle tube moves, under the pulling force of the spring, the medical dust-free cloth impregnated with iodophor can clean the surface of the puncture core. Therefore, when cleaning the contaminated lens, there is no need to pull out the lens from the patient's body, which improves the work efficiency of medical staff and reduces unnecessary surgical risks.
[0023] 2. For this new puncture sheath, the stopper can facilitate the staff to operate the puncture core, so as to reduce the interference probability between the instruments during the operation. The arc-shaped structure can conform to ergonomics, make the force on the puncture core more uniform, and make the puncture operation more stable. The groove can increase the surface roughness of the puncture needle tube and prevent it from slipping off the hands of the staff. BRIEF DESCRIPTION OF THE DRAWINGS
