Description
Technical field
This utility model relates to area of medical devices, is specifically related to one and has cutting thoracic cavity fiber thorax quill.
Background technology
Along with hydrothorax and pneumothorax are common diseases clinically, for the thoracic cavity of two class disease surgeries use widely.Except the blood caused by thoracic trauma, pneumothorax, outside Thorax operration hydrothorax, in recent years, because lung cancer morbidity rate and phthisical sickness rate increase year by year, patients with pleural caused by cancerous hydrothorax patient and tuberculosis is increased in a large number, this two classes patient often needs repeated multiple times thoracentesis, and making thus increases greatly to the demand in thoracic cavity clinically.
When hydrothorax is too much, thoracic cavity produces thoracic cavity fiber, cut off the hydrops of thoracic cavity, use existing thoracentesis needle cannot get rid of the whole hydrops of thoracic cavity, allow patient's repeat surgery drain the water away, increase the pain of patient, cut when taking out puncture casing, because sleeve pipe contacts closely with muscular tissue, be with secondary pain to patient during taking-up, needed improvement badly.
Utility model content
The purpose of this utility model is to provide a kind of medical thoracic cavity casing bit, cuts intrathoracic thoracic cavity fiber, and get rid of whole hydrops in thoracic cavity, simple to operate, improve procedure efficiency, alleviate the misery of patient, security performance is good.
This utility model provides a kind of medical thoracic cavity casing bit, comprise puncture casing and cutting part, puncture casing comprises clamping part and puncture portion, puncture portion is provided with opening, cutting part is plugged in puncture casing, and cutting part comprises installation portion, is positioned at the fixing hole of installation portion one end and interchangeable cutting edge, and cutting edge one end is bent to form hook, hook hasp is in fixing hole, and puncture portion is provided with the first set of blades and the second set of blades.The length of puncture casing is 15-20cm, and internal diameter is 3-6mm.Little to the wound of patient when performing the operation, avoid damaging chest tissue.First set of blades is screw-like.Second set of blades is screw-like.Puncture portion is taper.Will through thoracic cavity during convenient operation
In some embodiments, the first set of blades and the second set of blades circumference on puncture portion outer surface extends.Be conducive to the enforcement of puncturing operation.The blade direction of the first set of blades is clamping part dorsad, and the blade direction of the second set of blades is towards clamping part.Will through thoracic cavity when first set of blades is conveniently performed the operation, the second set of blades facilitates operation to terminate rear taking-up sleeve pipe.
Accompanying drawing explanation
The one medical thoracic cavity casing bit structural representation of a kind of embodiment that Fig. 1 provides for this utility model.
The puncture portion structural representation of a kind of medical thoracic cavity casing bit of a kind of embodiment that Fig. 2 provides for this utility model.
The cutting part structural representation of a kind of medical thoracic cavity casing bit of a kind of embodiment that Fig. 3 provides for this utility model.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, explanation is described in further detail to this utility model.
This utility model relates to a kind of medical thoracic cavity casing bit, as shown in Figure 1, Figure 2 and Figure 3, comprise puncture casing 1 and cutting part 2, puncture casing 1 comprises clamping part 11 and puncture portion 12, puncture portion 12 is provided with opening 121, cutting part 2 is plugged in puncture casing 1, cutting part 2 comprises installation portion 21, is positioned at fixing hole 22 and the interchangeable cutting edge 23 of installation portion 21 one end, cutting edge 23 one end is bent to form hook 231, link up with 231 hasps in fixing hole 22, puncture portion 12 is provided with the first set of blades 31 and the second set of blades 32.
Cutting part 2 comprises installation portion 21, is positioned at fixing hole 22 and the interchangeable cutting edge 23 of installation portion 21 one end.Cutting edge 23 one end is bent to form hook 231, links up with 231 hasps in fixing hole 22.Fixing hole 22 is arranged at the side of installation portion 21.Be provided separately cutting edge 23, be convenient for changing cutting edge 23, be conducive to cost-saving, recycle.
In order to make hook 231 easily be installed in fixing hole 22, the central axis of fixing hole 22 and the vertical line of installation portion 21 intersect.Formed by the centrage of fixing hole 22 and the vertical line of installation portion 21, angle is between degree is to 15 degree to 30 degree.In order to make hook 231 coordinate firmly with fixing hole 22, be provided with extension limit outside fixing hole 22, extension limit is held in hook 231.
Clamping part 11 is located at puncture casing 1 one end, puncture portion 12 is located at puncture casing 1 other end, formation is wholely set, puncture portion 12 is provided with opening 121, cutting part 2 is arranged on puncture casing 1 through opening 121, puncture casing 1 and cutting part 2 are metal material, conveniently cut through thoracic cavity with to thoracic cavity fiber, structure is simple, easy to operate, the turn of bilge 13 of puncture casing 1 coordinates cutting part 2, when performing the operation, rotate clamping part 11, cutting part 2 can rotate in thoracic cavity, cut off intrathoracic fiber, the hydrops of partition is discharged.
The length of puncture casing 1 is 15-20cm, and internal diameter is 3-6mm.Little to the wound of patient when performing the operation, avoid damaging chest tissue.The length of cutting part 2 is greater than the length of puncture casing 1, the diameter of cutting part 2 is less than the internal diameter of opening 121, puncture casing 1 is facilitated to be set on cutting part 2, the length of puncture casing 1 is applicable to thoracic cavity foremost when being 15cm, is applicable to thoracic cavity least significant end when the length of puncture casing 1 is 20cm, and puncture casing 1 internal diameter is little, little to the wound of patient when performing the operation, avoid damaging chest tissue, because puncture casing 1 internal diameter is little in operation, just very little to the wound of patient.
