Abstract

The utility model provides a closed type drainage positioning cutting device for chest cavities. The utility model is characterized in that the front end of the core part of a rectangular shell body is provided with a tip two-edge cutting knife of stainless steel, which can expand and contract forwards, and the back end of the shell body is provided with a pushing rod with a handle, which is connected with the tail part of the tip two-edge cutting knife of stainless steel; screw threads on the pushing rod are connected with a regulating nut which can regulate the pushing depth of the pushing rod, and a spring which causes the reset of the pushing rod. The utility model has the advantages of accurate positioning, no harm to nerves and blood vessels on ribs, simplicity and easy learning, and is a safe surgical instrument for closed type drainage operations for chest cavities.

Description

A kind of closed drainage of pleural cavity location cutter

Technical field

This utility model relates to a kind of closed drainage of pleural cavity operating theater instruments that is used for, especially a kind of closed drainage of pleural cavity location cutter.

Background technology

Pneumothorax is common clinically anxious principal characteristic disease, is in peril of one's life if rescue untimely meeting.Closed drainage of thoracic cavity operation is the most important method of rescuing the pneumothorax patient at present, its operation process is: having between two ribs at pneumothorax position with an osculum feeding of scalpel incision thoracic wall thoracic cavity, drainage tube is inserted osculum and fixing, the other end of drainage tube connects water-sealed drainage bottle, by drainage tube the liquid at pneumothorax position in the thoracic cavity is discharged, thereby reach the purpose of healing.But it is bigger with the scalpel operation easier to be covered with nerve and blood vessel on the rib, easily injures intercostal nerves and vascular complication, and therefore implementing this type of operation needs well-trained thoracic surgeon to be competent at.Especially at night, doctor on duty does not grasp the closed drainage of pleural cavity surgical skills, and the training thoracic surgeon can not arrive in the very nick of time again, and has incured loss through delay the best operation of patient opportunity.

Summary of the invention

This utility model provides a kind of easy, easy, safe and reliable closed drainage of pleural cavity to locate cutter for solving the technical problem that exists in the known technology.

The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is:

A kind of closed drainage of pleural cavity location cutter, the housing of cutter groove and be movably arranged on the stainless steel blade that can outwards stretch in the cutter groove and form in the rectangle front end of being made by macromolecule organic material has, the rear end of housing has the through hole that leads to the cutter groove, the screwed pushing ram that is connected with the stainless steel blade afterbody is installed in through hole, it is female and make the spring of stainless steel blade return that the adjusting that regulate to advance the degree of depth is installed on the pushing ram, at the afterbody of pushing ram handle is installed also; Described stainless steel blade is most advanced and sophisticated two-edged incision knife, and described housing front end is slick and sly cambered surface.

Advantage and the good effect that the utlity model has are: since in adorn telescopic most advanced and sophisticated two-edged incision knife the housing front end be the cambered surface of a slyness, be easy to be positioned between two ribs at pneumothorax position like this, when implementing cutting operation, most advanced and sophisticated two-edged incision knife is avoided rib and is stretched out along the cutter groove, can not injure epicostal nerve and blood vessel, make the closed drainage of pleural cavity operation safety reliable, in addition, because this utility model is easy, Yi Xue, made general medicine, the doctor of the basic clinical experience of surgery all can finish the closed drainage of pleural cavity operation process, has won the quality time for rescuing the pneumothorax patient.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is that the B of Fig. 1 is to view.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1, be shaped on the cutter groove 2 that leads to the housing front end, the most advanced and sophisticated two-edged incision knife 3 of telescopic rustless steel is housed in the cutter groove at rectangular housing 1 heart.Be shaped on the centre bore 8 that leads to cutter groove 2 in the rear end of housing 1, as shown in Figure 2, the pushing ram 4 that is connected with the most advanced and sophisticated two-edged incision knife of rustless steel afterbody be installed in the centre bore.For the stroke of regulating pushing ram with make the most advanced and sophisticated two-edged incision knife of rustless steel return, also be shaped on screw thread on the pushing ram, also be equipped with on pushing ram by screw thread and regulate female 6 and spring 5, the afterbody of pushing ram also is equipped with slick and sly handle 7.For housing 1 front end accurately is positioned between two ribs, also be shaped on smooth circular arc 8 at the housing front end.As shown in Figure 3.

Using method:

After accurate location, sterilization, local anaesthesia, the female 6 good depths of cut of finding out during by local anaesthesia of thoracic wall thickness adjusted are regulated in turn, left hand is held this utility model the arc surface 8 of housing front end is fixed between two ribs, with thoracic wall at an angle of 90, right hand vertical pressing handle 7 is downward, makes pushing ram 4 drive the most advanced and sophisticated two-edged incision knifes 3 of rustless steels and enters fast and reach the thoracic cavity, right hand release handle, pushing ram is withdrawing under the effect of spring 6, and return is finished the pneumothorax incision surgery.

Claims

1. a closed drainage of pleural cavity is located cutter, the housing of cutter groove and be movably arranged on the stainless steel blade that can outwards stretch in the cutter groove and form in the rectangle front end of being made by macromolecule organic material has, it is characterized in that: the rear end of housing has the through hole that leads to the cutter groove, the screwed pushing ram that is connected with the stainless steel blade afterbody is installed in through hole, it is female and make the spring of stainless steel blade return that the adjusting that regulate to advance the degree of depth is installed on the pushing ram, at the afterbody of pushing ram handle is installed also; Described stainless steel blade is most advanced and sophisticated two-edged incision knife, and described housing front end is slick and sly cambered surface.
