Description

Microchannel hemostatic electrocoagulator suitable for percutaneous nephrolithotripsy

Technical Field

The utility model relates to the field of medical instruments for urinary surgery, in particular to a microchannel hemostatic electrocoagulator suitable for percutaneous nephrolithotripsy.

Background

Urinary calculi are one of the most common diseases of urinary surgery. At present, the incidence rate of the upper urinary tract calculus, especially kidney calculus, is high, and the main treatment methods of the kidney calculus comprise three methods: extracorporeal shock wave lithotripsy, percutaneous nephrolithotripsy and ureteroscope lithotripsy. Percutaneous nephrolithotripsy is a modern surgical minimally invasive technique for in vivo lithotripsy and lithotripsy by establishing a percutaneous renal channel. By establishing an operative path from the skin to the kidneys, the stones are broken and washed out using laser or air pressure ballistic jets.

The operation of hemostasis is that the hemostasis by compression is carried out at the hemostasis by compression bleeding point of the indwelling nephrostomy tube in the operation channel, although widely used, the indwelling nephrostomy tube has certain defects:

(1) The application time of the postoperative analgesic is longer;

(2) The risk of traction bleeding, tube removal and the like is easily caused, the occurrence rate of postoperative complications is increased, and the medical expense and time cost of patients are increased by pulling out the tube again.

(3) The patient is not dared to move and the time of the bed leaving movement is delayed, a healing period of 5-7 days is usually required, and during the period, the fistula is placed on the body of the patient, so that a plurality of inconveniences are brought to the movement and rest of the patient;

therefore, based on the existing electric coagulation firing hemostasis principle and an open operation electric coagulation hemostasis mode, the electric coagulation hemostasis mode can be adopted to stop bleeding of the intrarenal bleeding point so as to omit the use of the indwelling nephrostomy tube.

However, the existing electrocoagulation hemostasis mode is mainly applied to open surgery. However, in the age of popularization of minimally invasive surgery, the electrocoagulation hemostatic instrument has obvious limitations, especially in percutaneous nephrolithotripsy, the established percutaneous renal channel is deep and fine, and the existing electrocoagulation hemostat cannot enter the body to stop bleeding through the minimally invasive channel at all and is inconvenient to be used in combination with the nephroscope.

In view of this, a microchannel hemostatic electrocoagulator suitable for percutaneous nephrolithotripsy was designed.

After the lithotripsy is finished, the lithotripsy instrument such as laser and air pressure ballistic lithotripsy rod is taken out from the channel, and then the electrocoagulation hemostat is placed in the channel and can reach the appointed hemostasis point.

The electric coagulation bar 2 comprises a connecting rod 2.1 and an electric coagulation head 2.2 connected with the front end of the connecting rod 2.1, and the electric coagulation bar 2 is connected with the connecting part 1.1 in a matched manner through the connecting rod 2.1 to realize the installation of the electric coagulation bar and the electric coagulation handle 1. The connecting rod 2.1 and the electrocoagulation head 2.2 are both made of conductive metal, and in the embodiment, medical stainless steel is generally selected. In this embodiment, the front end and the side end of the electrocoagulation head 2.2 may be arranged in an arc shape, which is beneficial to contact with the hemostatic site. Among them, the electrocoagulation head 2.2 may be preferably provided in a spherical shape.

When the electric coagulation device is used, the connecting rod 2.1 is connected with the connecting part 1.1 in a matched manner, the electric coagulation rod 2 stretches into a patient body through an operation channel established on the skin of the patient, the electric coagulation head 2.2 is placed at a bleeding point through an endoscope stretching into other operation channels for observation, the control switch 1.2 is pressed, a power supply is communicated with the electric coagulation rod 2, current is transmitted to the electric coagulation head 2.2 through the connecting rod 2.1, and the electric coagulation hemostasis is carried out on the bleeding point through the electric coagulation head 2.2.

Thereby overcoming the defect that the fistula needs to be left for a long time after the operation is performed by using the fistula to stop bleeding, and reducing the recovery period of patients.

As a specific embodiment of the mating connection of the connecting part 1.1 and the connecting rod 2.1, the connecting part 1.1 is internally provided with a mounting channel, and the connecting rod 2.1 can be inserted into the connecting part 1.1. Because the weight of the electric coagulation bar 2 is lighter, the technical effect of the cooperation installation of the connecting rod 2.1 and the connecting part 1.1 can be met through the way of being spliced with the connecting part 1.1, and meanwhile, the electric coagulation bar 2 and the electric coagulation handle 1 can be quickly installed through the way of being spliced with the connecting part 1.1 through the connecting rod 2.1.

Because the connecting rod 2.1 and the electric coagulation head 2.2 are both made of conductive metal materials, the risk of electric coagulation caused by contact of the connecting rod 2.1 with normal tissues in a patient body exists when electric coagulation hemostasis is carried out. Therefore, an insulating layer is provided on the outside of the connecting rod 2.1. The insulating layer may be an insulating paint sprayed on the outer side of the connecting rod 2.1, or an insulating substance coated on the outer side of the connecting rod 2.1, for example, rubber is coated on the outer side of a conductive object for insulation. Furthermore, in order to ensure good conductive effect between the electrocoagulation handle 1 and the connecting rod 2.1, an insulating layer is not coated on the outer side of a section of the connecting rod 2.1 inserted into the connecting part 1.1.

By using the endoscope and the electric coagulation device to extend into the body of a patient from two operation channels built on the skin of the patient respectively to perform electric coagulation hemostasis, the observation effect of the endoscope is poor, the hemostasis condition of the electric coagulation device cannot be observed intuitively, therefore, the electric coagulation rod 2 can penetrate through the instrument channel of the kidney mirror 3, and the electric coagulation head 2.2 can extend out from the end part of the instrument channel. The nephroscope 3 is an electronic instrument used in percutaneous nephroscope operation, an instrument channel for inserting different long-handle surgical instruments is formed in the electronic instrument, and an illumination light source and a camera are arranged at the end of the electronic instrument, so that the operation condition of the instruments can be intuitively transmitted to a display for a doctor to observe.
