Abstract
The utility model relates to a combinative perforator for thoracic operation, which is used for clinical biopsy of thoracic wall (soft tissue rib, pleura) and closed thoracic drainagevarious pneumopyothorax and internal fistula of thoracic cavity, etc.) The utility model can simplify the conventional operation to single man and single instrument operated operation which can be accomplished by one time, having the advantages of high work efficiency, safe and easy operation, and less injury and bleeding, while the pain of the patient can be lightened.
Description
This utility model is to carry out the biopsy art of thoracic wall (soft tissue rib, pleura) and the combination type thoracic wall hole making drill of closed drainage of thoracic cavity operation (all kinds of pyopneumothoraxs, thoracic cavity internal fistula etc.) on a kind of clinical medicine.
Up to now, on the clinical medicine traditional " local organization excision and closed drainage of thoracic cavity operation " mode is all adopted in thoracic wall biopsy and closed drainage of pleural cavity at home and abroad, require it technical strong, the proficiency level is higher, needs the above professional's close fit of 3 people.Trivial operations uses apparatus more, one section rib of special amputation, and very easily injured nerve and blood vessel, damage range is big.For drainage of pleural cavity, wound is big, and the postoperative healing is poor, brings very big misery to patient, has increased the postoperative care difficulty.
The inventor is in conjunction with the above-mentioned clinical middle problem that exists, and through research for a long time, repetition test makes this novel thoracic wall perforate apparatus finally.Its purpose is once finished biopsy or closed drainage of thoracic cavity operation.
This utility model is to be combined by three parts.(1) directed ratchet handle Fig. 2 of band cone screw drilling rod.(2) crown saw Fig. 3.(3) dilator Fig. 4.Be the one use with mutually combining inside and outside three parts.This apparatus has adopted rustless steel or medical metal material manufacturing, and directed ratchet handle adopts the commodity of selling on the market.Directed ratchet handle Fig. 2 of cone screw drilling rod is housed, and by directed ratchet handle (1), square kelly (2) is embedded in the Spring Card (3) in the drilling rod, and cone screw shape drill bit (4) has the end (2 ') of projection to constitute.Crown saw Fig. 3 is made of crown saw (11) drilling rod (2) with square hole bourrelet end tooth.Accompanying drawing:
Fig. 1 assembled sectional view of the present utility model.
The directed ratchet handle sketch map of Fig. 2 band cone screw drilling rod.
Fig. 3 crown saw sketch map.
Fig. 4 dilator sketch map.
Fig. 2 is installed in directed ratchet handle (1) with cone screw drilling rod (2), forms the directed ratchet handle integral body of band cone screw drilling rod.
Fig. 3 crown saw (11) is supporting with cone screw drilling rod (2).The square hole of drilling rod and crown saw is and is slidingly matched.
Fig. 4 dilator is made of the identical groove (7) of tooth bar turn-knob (10) and support arm (8) expansion page or leaf (5) anti-slop serrations (6), tooth bar (9).
Formation of the present utility model as mentioned above.Its best applications effect, crown saw (11) cone screw drilling rod (2) supporting with dilator in outer facies association be one.Earlier skin is cut an osculum, vertically thrust immediately, direct reach and desire perforate position rib.After rotating ratchet handle (1) made the drilling rod clockwise direction rotate for 2～3 weeks, apparatus promptly was fixed on the rib by cone screw drill bit (4).Then counterclockwise rotate split extension device tooth bar turn-knob (10), two expansion pages or leaves of dilator are expanded outwardly along tooth bar (9).Strut the edge of a knife, this moment, rib surface directly showed.Under the effect of expansionary force and rib tissue contracts power, produced the effect that prevents the dilator slippage.Again crown saw (11) is promoted along the AA direction, by the automatic fix in position of drilling rod Spring Card, clockwise direction rotating ratchet handle then, crown saw rotates with drilling rod (2) and cuts the rib tissue, until complete dialysis.Be filled with rib and the tissue under the saw this moment in the crown saw, extract apparatus out, takes out biological tissue.Institute's perforate can be assigned drainage tube.The crown saw model can be selected for use according to clinical needs.
Main feature of the present utility model is, a kind of apparatus, and the one man operation once finishes, and is safe and simple to reach, and rapidly, reduces damage, reduces misery, substituted the wall of the chest biopsy operation of traditional type and cut the rib closed drainage of thoracic cavity operation.
Claims (3)
1, a kind of medical combination type thoracic wall hole making drill, it is characterized in that being square and studding with spring card slot (3) and metal spring card (3) by main body, its front end is cone screw shape (4), and there is directed ratchet handle and the crown saw and the dilator combination formation of the cone screw drilling rod of projection the rear end.
2, according to the described combination type thoracic wall of claim 1 hole making drill, the crown saw (11) that it is characterized in that it is with square hole bourrelet end tooth.
3, according to the described combination type thoracic wall of claim 1 hole making drill, the square hole that it is characterized in that cone screw drilling rod (2) and crown saw (11) is and is slidingly matched and orientation is rotatably assorted.
