Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to improvement of a suction tube mainly used for degreasing subcutaneous fat and the like during plastic surgery using a defatting suction device. The purpose of the present invention is to shorten the working time, to improve accuracy, and to heal wounds at an early stage.

(Prior art) Conventionally, the third method is used for suction removal of subcutaneous fat using a degreasing suction device.
A suction tube as shown in the figure has been used.

This is because a thin tubular air supply pipe c is integrally inserted into a hollow suction pipe a, and an opening b of the suction pipe a and an opening d of the air supply pipe c are both directed in the longitudinal axis direction. This is inserted into the incised subcutaneous part such as the abdomen with its tip facing, and air is intermittently supplied from the opening d through the air supply pipe c to the vicinity of the opening of the suction pipe a. The tissue to be defatted is sucked through the opening b while the suction tube a
The treatment is performed while sucking into an external degreasing suction device (not shown) via the.

However, since the opening direction of the conventional suction tube described above is oriented in the direction of its longitudinal axis, it is easy to aspirate unnecessarily adipose tissue, including fat immediately below the subcutaneous tissue, during surgery, and to reduce blood vessels and nerves The present inventor has improved this point because of the problem of easily damaging tissues, etc., and developed a structure in which the opening direction was opened in a direction different from the longitudinal axis of the suction tube. -
Published to the public as 94554.

(Problems to be Solved by the Invention) The suction tube having the structure described in Japanese Utility Model Application Laid-Open No. 2-94554 was significantly more efficient than the conventional type and could improve workability.

However, since the subcutaneous adipose tissue is tightly connected to the subcutaneous tissue, the removal operation is not easy.
For this reason, the suction tube is reciprocated in the subcutaneous tissue such as the abdomen many times, so that the blood vessels and nerve tissue of the subcutaneous tissue are easily damaged, and it is almost impossible to remove the fat tissue in the back from the incision. .

(Means for Solving the Problems) The present invention solves the above-mentioned various problems in the prior art, and facilitates the separation of the fat tissue from the subcutaneous tissue and the removal of the fat tissue in the back from the incision. Specifically, a hollow suction tube in which a head portion having a suction port opened at the tip is detachably attached, and a supply tube for feeding air or liquid near the tip of the suction tube. Wherein the suction port of the head portion is opened in a direction different from the longitudinal axis of the suction tube, and a cutting blade is formed at an edge of the suction port. The present invention relates to a surgical suction tube.

(Action) Since the suction port of the suction tube is opened in a direction different from the longitudinal axis thereof, not only can fat tissue directly under the subcutaneous tissue be easily removed during surgery, but also fat tissue and blood vessels to be left. It is possible to perform the operation while easily avoiding tissues such as nerves, and the cutting edge is formed at the edge of the suction port. Adipose tissue can also be easily removed.

In addition, since the head portion can be freely replaced, the head portion having cutting blades of various shapes can be arbitrarily replaced as needed, and the operation operation is further facilitated.

In addition, since the supply tube is attached, intraoperative cleaning work and suction of cut fat tissue are further facilitated, and the supply tube can be used not only for gas such as air but also for injection of Ringer's solution and other various solutions. can do.

(Embodiment) Hereinafter, the specific contents of the present invention will be described based on the embodiment shown in FIGS. 1 and 2, wherein 1 is a suction pipe, 3 is a head section, 4 is a supply pipe, 6 is a base section, Reference numeral 7 denotes a connection part connected to the suction pipe 1, and reference numeral 8 denotes a connection part connected to the supply pipe.

The suction tube 1 has a tubular shape with a hollow portion 2 inside, and has a proximal end fixed to the base portion 6 and a female screw portion (not shown) provided on the inner peripheral surface of the distal end.

The head portion 3 has substantially the same diameter as the suction tube 1 and has a hollow interior, and has one end closed in a circular shape, and a suction port 2a opened in a direction different from the longitudinal axis X thereof. A cutting blade 3a is formed at the opening edge of the mouth 2a.

Further, the head part 3 has a male screw part 3b on the outer peripheral surface of the other end.
And screwed into a female thread (not shown) at the tip of the suction tube 1 to be integrally formed as shown in FIG.

The supply tube 4 is also the suction tube 1 having a hollow portion 5 inside.
The suction tube 1 has a smaller diameter than the suction tube 1 and is integrally formed by welding or an adhesive, etc., and has an opening 5a near the tip of the suction tube 1 and a base end thereof. It is fixed to the base 6.

In the above embodiment, the supply pipe 4 is attached to the outside of the suction pipe 1. However, the present invention is not limited to this. The supply pipe 4 is attached to the inner circumference of the suction pipe 1. You may.

The opening position and the opening angle of the suction port 2a opened in the head portion 3 and the shape thereof can be variously changed, and the cutting blade formed on the opening edge can be changed.
Various design changes are also possible for the formation position and angle of 3a.

Specifically, the cutting blade 3a is formed over substantially the entire peripheral surface of the suction port 2a, or the longitudinal axis X of the head portion 3 is formed.
May be formed opposite to each other, or in addition thereto, may be formed so as to oppose both ends in a lateral direction orthogonal to the longitudinal axis X.

The means for connecting the head portion 3 to the suction tube 1 is not limited to the above-mentioned screwing means using a male screw and a female screw. Various connecting means such as a rotating hook type to be worn are conceivable.

Further, the head portion 3 can be arbitrarily exchanged as needed, with various configurations of the position and shape of the suction port 2a and the position and shape of the cutting blade 3a.

In the configuration of the above-described embodiment, the connection part 7 of the suction pipe 1 and the connection part 8 of the supply pipe 4 are respectively connected to the degreasing suction device main body via connection hoses.

At the time of use, the base 6 is gripped, air or a liquid such as Ringer's liquid is intermittently supplied from the supply pipe connection section 8, and air is supplied or supplied from the supply port 5 a while the head section 3 of the suction pipe 1 is supplied.
Is inserted into the treatment site from the incision site, and the head portion 3 is advanced or retracted or rotated in the circumferential direction to cut the fat tissue to be degreased with the cutting blade 3a.
While the cutting is performed, suction is performed into the suction pipe 1 from the suction port 2a, and the suction pipe 2 is sent from the connection portion 7 to the suction device main body to be collected.

(Effects of the Invention) As described above, in the present invention, since the suction port is opened in a direction different from the longitudinal axis of the suction tube, the fat tissue just under the subcutaneous area can be easily removed during the operation. In addition, the operation can be performed while easily avoiding tissues such as adipose tissue, blood vessels, and nerves to be left, and since the cutting edge is formed at the edge of the suction port, the removal of adipose tissue is facilitated. Not only that, the fat tissue at the back can be easily removed from the incision.

In addition, since the head portion can be freely replaced, the head portion having cutting blades of various shapes can be arbitrarily replaced as needed, and the operation operation is further facilitated.

Further, since the supply tube is attached to the suction tube, not only the suction of the cut fat tissue during the operation is further facilitated, but also the washing of the cut portion is completed, and the working time is reduced.

Moreover, the supply pipe can be used not only for gas such as air, but also for injection of Ringer's solution and other various solutions.
