Detailed Description
Referring to fig. 1-11, the present invention provides 2 embodiments of the technical solution:
example 1
As shown in fig. 1, 6 and 9, a needle-shaped incision knife under duodenoscope is designed, which comprises a total liquid cavity 1, an upper opening and a lower opening which are communicated with the total liquid cavity 1, and a human body insertion hose device 5 communicated with the lower opening, wherein the human body insertion hose device 5 is an existing long and thin pipeline of the operation, and the material for inserting the human body hose device 5 can be the related material in the incision knife in the prior art. The utility model discloses a its improvement lies in the structure of needle-like incision sword under the duodenoscope: the liquid duct 56 and the guide wire duct 57 for the movable insertion of the guide wire 52 are arranged in parallel when the human body hose device 5 is inserted, the guide wire 52 is axially movably pulled to disturb the fluctuation of the soft side wall of the partition between the liquid duct 56 and the guide wire duct 57 so as to prevent blockage, and the fluctuation of the soft side wall of the partition can influence the liquid duct 56. The pore diameter of the liquid pore passage is preferably set to 3 to 8 mm. The liquid pore 56 and the guide wire pore 57 are expanded separately, so that the guide wire 52 can be stretched into the human body for treatment while the liquid suction or injection is smoother, and when the operation is performed, the operator inserts the human body hose device 5 into the duodenum, and when the intestinal tract liquid suction detection or the liquid injection is needed to treat the intestinal tract of the human body, the guide wire 52 does not block the flow channel, so that the infusion and the liquid suction are smoother.
The outer end of the guide wire 52 is often connected with an electric knife in medical clinic, and the high-frequency electric knife is an electric surgical instrument for replacing a mechanical scalpel to cut tissues. The tissue is heated when high-frequency high-voltage current generated by the tip of the effective electrode is conducted through the guide wire 52 and is contacted with the human body, so that the separation and coagulation of the tissue of the human body are realized, and therefore, when the guide wire 52 is electrified, the guide wire 52 can achieve the purposes of cutting and electric coagulation hemostasis in the duodenum.
As shown in fig. 1-6, the device 5 for inserting a body tube comprises a tube body 51 having a liquid channel 56 and a guide wire channel 57 which are parallel to each other, a guide wire 52 inserted into the guide wire channel 57, and a plurality of balls 53 fixedly sleeved on the guide wire 52. Preferably, an arc-shaped groove 55 matched with the movable clamping of the sphere 53 is formed on the soft side wall of the middle partition between the guide wire pore channel 57 and the liquid pore channel 56, and the symmetrical tolerance of the curvature radius of the arc-shaped groove 55 and the radius of the sphere 53 is +/-0.15 cm. And the arc-shaped groove 55 is only arranged on one side of the soft side wall of the septum of the guide wire pore canal 56. Generally, when the liquid duct 56 is not blocked, the plurality of spheres 53 on the guide wire 52 are clamped in the arc-shaped groove 55, when the liquid duct 56 is blocked and is not smooth, because the medical guide wire 52 has certain rigidity and toughness and the tube body 51 has flexibility, an operator can pull the guide wire 52 back and forth to drive the dry spheres 53 thereon to repeatedly collide and disturb the liquid duct 56 and share one side of the middle partition soft side wall of the tube body 51 with the guide wire duct 57, and the disturbance of the middle partition soft side wall transmits force to the liquid duct 56 through the other side, so that the fluctuation of the blockage inside the liquid duct 56 is facilitated to be loosened, the intestinal tract liquid is pumped or the liquid is injected to pass through the liquid duct 56 more smoothly, and the operation safety effect is greatly improved.
Meanwhile, a limiting ring 54 for preventing the guide wire 52 from slipping in the duodenum of the human body can be fixedly sleeved at one end of the guide wire 52 close to the total liquid cavity 1, so that the risk of falling into the human body is reduced.
Example 2
As shown in fig. 4 and 5, based on embodiment 1, the total liquid cavity 1 may be improved in design, and the total liquid cavity 1 may have a cylindrical cavity structure, which is specifically as follows: the upper opening of the total liquid cavity 1 is provided with two first liquid ports 3 and two second liquid ports 4, the first liquid ports 3 and the second liquid ports 4 are inserted into a human body hose device 5 to form a Y-shaped structure, liquid medicine can be injected through the first liquid ports 3, and human body liquid can be extracted from the second liquid ports 4.
The total liquid cavity 1 is also rotatably connected with a reversing valve switch 2 which can rotate along the opposite direction to alternately control the opening and closing of the first liquid opening 3 and the second liquid opening 4, meanwhile, the first liquid opening 3 and the second liquid opening 4 are respectively communicated with two external pumps, one input pump and the other output pump are selected for the two external pumps, the two external pumps are common pumps in medical treatment and can pump liquid or inject liquid, the reversing valve switch 2 is used for rotating and adjusting in order to switch the first liquid opening 3 and the second liquid opening 4, and the reversing valve switch 2 can be used for alternately plugging the first liquid opening 3 or the second liquid opening 4.
When the reversing valve switch 2 rotates to block the first liquid opening 3, the second liquid opening 4, the inner cavity of the total liquid cavity 1 and the human body hose inserting device 5 are communicated, and human body intestinal tract liquid can be extracted for detection; when the reversing valve switch 2 rotates to block the second liquid opening 4, the first liquid opening 3, the inner cavity of the total liquid cavity 1 and the inserted human body hose device 5 are communicated, and medical liquid required by medical treatment can be injected to treat intestinal tracts.
The head part and the rotating part of the reversing valve switch 2 are both matched and sleeved with a liquid leakage prevention leather sheath, so that the sealing performance of the total liquid cavity 1 is improved. The head of the reversing valve switch 2 is of an arc-shaped structure, and the head of the reversing valve switch 2 is limited in an arc-shaped groove 55 which is formed in the bottom of the total liquid cavity 1 in a matching mode. When the reversing valve switch 2 is rotated, the reversing valve switch 2 can be more stably rotated. To total fluid cavity 1's improvement, realized the effect of Y type tee bend switching-over for changeable internal liquid of taking out detects or annotates the liquid medicine treatment, makes things convenient for the operation to use, and the simple structure of this design makes things convenient for the adjunctie therapy of operation in-process, and the effect is fit for popularizing to hepatobiliary branch of academic or vocational study and uses more.
As shown in FIG. 11, the head of the switch 2 of the reversing valve can be further modified to be two symmetrical heads, so that when the switch is rotated, the two heads can simultaneously block the first liquid port 3 and the second liquid port 4, thereby independently completing the electrocoagulation hemostasis operation of the guide wire 52.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments still fall within the scope of the technical solution of the present invention.
