Abstract
The utility model provides a sliding thoracic cavity and abdominal cavity puncture needle, which comprises an internal needle, a bushing that is arranged outside the internal needle, a guide sleeve that is arranged outside the bushing, a slipping cavity that is provided for the guide sleeve and a sliding block that is arranged outside the upper part of the bushing and in the sliding cavity of the guide sleeve. The utility model has the advantages of simple puncture operation, facility for controlling and no injury toward the organs of the human body.
Description
Technical field
This utility model relates to medical apparatus and instruments, is a kind of slidingtype splanchnocoel puncture needle.
Background technology
The splanchnocoel puncture needle that uses in each hospital is a kind of improved structure at present, it has certain advantage with respect to the structure before improving, but find that in use still there is deficiency in it: can make the excessive influence of being exerted pressure of potential lacuna when using clinically, potential lacuna is disappeared, tissue is produced damage; Difficult location etc.Owing to difficult elimination of deficiency that its exists, use when generally setting up pneumoperitoneum clinically with this puncture needle.
Summary of the invention
The purpose of this utility model is, a kind of slidingtype splanchnocoel puncture needle is provided, and it is easy to make it have a puncture procedure, is easy to control, to advantages such as human internal organ not damageds.
This utility model is achieved through the following technical solutions for achieving the above object: slidingtype splanchnocoel puncture needle comprises interior pin, the periphery mounting sleeve of interior pin, sleeve pipe periphery mounting guide sleeve, guide pin bushing is provided with sliding cavity, and telescopic upper periphery connects slide block, and slide block is positioned at the sliding cavity of guide pin bushing.The needle end of interior pin is provided with first inclined-plane and second inclined-plane, and first inclined-plane is connected with second inclined-plane.Offer through hole on the telescopic sidewall.On the telescopic outer wall scale is set.
The utility model has the advantages that: easy to operate, the excessive influence of being exerted pressure of potential lacuna can not appear, thereby when implementing the splanchnocoel puncture, potential lacuna is disappeared, because when injection or drain, syringe needle contracts in sleeve pipe, so the organ injury that has caused to the patient when having avoided operate miss has particularly shortened needle length, further guaranteed human internal organ is not produced any damage etc.
Description of drawings
Accompanying drawing 1 is this utility model structural representation; Accompanying drawing 2 is plan structure sketch maps of accompanying drawing 1.
The specific embodiment
1 is interior pin among the figure, the periphery mounting sleeve 5 of interior pin 1, and sleeve pipe 5 periphery mounting guide sleeve 4, guide pin bushing 4 is provided with sliding cavity 3, and the upper periphery of sleeve pipe 5 connects slide block 2, and slide block 2 is positioned at the sliding cavity 3 of guide pin bushing 4.In order further guaranteeing human internal organ not to be produced damage, first inclined-plane 7 to be set and 8, the first inclined-planes 7, second inclined-plane are connected with second inclined-plane 8 in the needle end of interior pin 1.Can on the sidewall of sleeve pipe 5, offer through hole 6 for the ease of drain or injection.For the ease of control operation scale 9 can be set on the outer wall of sleeve pipe 5.Sleeve pipe 5 described in the utility model moves up and down (move left and right of shown position) along interior pin 1, and the shift motion of sleeve pipe 5 is the length of sliding cavity 3.Pin 1 has cavity in described in the utility model, during this practical use, interior pin 1 is inserted desired location in the splanchnocoel of human body, promote slide block 2 again, driving sleeve pipe 5 enters in the human body splanchnocoel, the syringe needle of interior pin 1 is inserted in the sleeve pipe 5, syringe needle is to the injury of human internal organ when having avoided drain or injection again.Because the inclined-plane of syringe needle described in the utility model is to be connected to form by two inclined-planes, has shortened the length of syringe needle, guaranteed that further puncture needle is when being easy to puncture, to the human internal organ not damaged.
