Abstract
This utility model provides a kind of microtrauma puncture external member, belong to medical instruments field, it is characterized in that: comprise nook closing member, convergent divergent channel and trocar sheath, described convergent divergent channel and trocar sheath is dismountable is set in outside nook closing member, nook closing member is arranged in convergent divergent channel and trocar sheath movably.This utility model structure is simple, be easy to operation, first with the puncture of fine needle core, the damage that inserting needle path is organized can be reduced, minimizing complication, reboots convergent divergent channel and trocar sheath assembly enters focus, withdraws from nook closing member and convergent divergent channel subsequently, set up escape way, to carry out radio-frequency (RF) ablation and to get the operation of pathological tissue.
Description
technical field:
The present invention relates to medical instruments field, be specifically related to a kind of microtrauma puncture external member being Minimally Interventional Therapy (radio-frequency (RF) ablation) and acquisition Pathologic specimen and setting up escape way.
background technology:
Radio-frequency ablation procedure is a kind of Minimally Interventional Therapy technology, directly inserts intralesional by means of the image technology location such as ultrasonic or CT and guiding radio frequency needle, and make focus local organization produce high temperature by radio-frequency (RF) energy, drying is finally solidified and deactivation soft tissue and tumor.
Radio frequency needle often directly punctures, and because radio frequency needle is comparatively thick, the tissue injury caused is comparatively large, and repeated localised puncture adjustment is carried out at the position not utilizing lung etc. easily to produce complication; And the at present conventional trocar setting up operating walk way is pin and puncture together with managing, the probability of damage can not be reduced.
utility model content:
For the defect that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of microtrauma puncture external member, and its structure is simple, and be easy to operation, puncture needle is tiny, and tissue injury is little, decreases the occurrence probability of complication.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of microtrauma puncture external member, it is characterized in that: comprise nook closing member, convergent divergent channel and trocar sheath, described convergent divergent channel and trocar sheath is dismountable is set in outside nook closing member, described nook closing member comprises the hard pin of front end and the guide wire of rear end, described convergent divergent channel is the tubular structure of hollow, be positioned at outside nook closing member, comprise front end conically enlarged portion, first tubular body in stage casing and the external thread structure of tail end, described enlarged portion offers through hole foremost, described trocar sheath is the tubular structure of both ends open, be positioned at outside convergent divergent channel, comprise the female thread structure that the second tubular body and afterbody match with the external thread structure of convergent divergent channel tail end.
Further setting of the present utility model is:
Described nook closing member is marked with scale.
Described through-hole diameter is more than or equal to the diameter of nook closing member.
The second described tubular body and the first tubular body isometric, the length of described external thread structure 0.5 cm ~ 1cm longer than the length of female thread structure.
The internal diameter of the second described tubular body is greater than the external diameter of the first tubular body.
Operation principle of the present utility model and beneficial effect as follows: this utility model structure is simple, and be easy to operation, first use fine needle aspiration, fine needle core can reduce the damage that inserting needle path is organized, and reduces complication, is convenient to repeatedly adjust position operation; Again by convergent divergent channel and trocar sheath assembly, convergent divergent channel front end enlarged portion auxiliary under enter focus, tailing screw flight structure of outwarding winding subsequently, withdraws from nook closing member and convergent divergent channel, completes the foundation of escape way, to carry out radio-frequency (RF) ablation and to get the operation of pathological tissue.
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
accompanying drawing illustrates:
Fig. 1 is the overall structure schematic diagram of this utility model embodiment;
Fig. 2 is the Split type structure schematic diagram of this utility model embodiment.
detailed description of the invention:
A kind of microtrauma puncture external member of the present utility model, comprises nook closing member 1, convergent divergent channel 2 and trocar sheath 3 as shown in Figure 1 and Figure 2, and described convergent divergent channel 2 and trocar sheath 3 are removably set in outside nook closing member 1, and nook closing member 1 is arranged in convergent divergent channel 2 and trocar sheath 3 movably; Described nook closing member 1 is made up of the hard pin 11 of front end and the guide wire 12 of rear end, and the hard pin 11 of front end is for being punctured to targeted site and guiding convergent divergent channel 2, trocar sheath 3, and the guide wire 12 of rear end is convenient to the later stage and is withdrawn from by nook closing member 1; Described nook closing member 1 is marked with scale, so that the lesions position gone out according to image location Calculation such as ultrasonic or CT, accurately punctures; Convergent divergent channel 2 is the tubular structure of hollow, be positioned at outside nook closing member 1, comprise front end conically first tubular body 22 in enlarged portion 21, stage casing and the external thread structure 23 of tail end, described enlarged portion 2 offers through hole 24 foremost, described through hole 24 diameter is more than or equal to the diameter of nook closing member 1, be convenient to nook closing member 1 and insert and withdraw from convergent divergent channel 2, first tubular body 22 in stage casing is under the auxiliary drive of enlarged portion 21, and the path along nook closing member 1 enters focus; Trocar sheath 3 is the tubular structure of both ends open, be positioned at outside convergent divergent channel 2, comprise the female thread structure 32 of the second tubular body 31 and tail end, described external thread structure matches with the external thread structure 23 of convergent divergent channel 2 tail end, is convenient to make convergent divergent channel 2 combine with outer tube sleeve 3 or be separated; The second described tubular body 31 is isometric with the first tubular body 22 of convergent divergent channel 2, the length 0.5 cm ~ 1cm longer than the length of female thread structure of described external thread structure 32, hold for hand, when being convenient to convergent divergent channel 2 to be separated with outer tube sleeve 3, screwed out from the female thread outer tube sleeve 3 by the external screw thread 23 of convergent divergent channel 2, the internal diameter of the second tubular body 32 is greater than the external diameter of the first tubular body 22.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure transformation utilizing this utility model description to do; or directly or indirectly use the technical field being attached to other Related products, be all in like manner included in scope of patent protection of the present utility model.
