Prostate Surgery Catheter Kit with Balloon Stopper and Injection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current prostate surgery and treatment methods face challenges in effectively managing blood flow and cooling during procedures like transurethral resection of the prostate (TURP) and heat treatments, leading to increased bleeding and reduced treatment efficacy.
Innovation Solution
A kit comprising a catheter with a balloon stopper unit, injection connection, and a hollow tip made of PEEK, along with syringes containing adrenaline and anesthetic agents, is used to suppress blood flow and provide precise medication delivery, including botulinum toxin and penicillin, to minimize bleeding and enhance treatment outcomes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional catheters are used for prostate surgery, then basic drainage function is provided, but blood flow control and treatment efficacy are insufficient
Solution Approach 1:
The patent combines multiple functions into a single integrated catheter system: drainage lumen for urine drainage, balloon stopper unit for blood flow control, injection tube for medication delivery, and hollow tip for targeted injection. This merging of functions resolves the contradiction by providing comprehensive control over bleeding and treatment delivery without requiring multiple separate devices.
Solution Approach 2:
The balloon stopper unit is inflated before the surgical procedure to establish blood flow control and maintain prostate temperature. The injection tube is pre-positioned with medications (adrenaline and anesthetic agents) ready for delivery. These preliminary actions prevent bleeding and cooling during the subsequent surgical intervention, resolving the contradiction between treatment efficacy and bleeding control.
2Temperature
If blood flow to prostate is not suppressed, then natural blood supply is maintained, but cooling down occurs during heat treatment and bleeding increases during surgery
Solution Approach 1:
The patent introduces adrenaline as an intermediary substance injected through the hollow tip into the prostate tissue. Adrenaline acts as a vasoconstrictor that reduces blood flow while maintaining tissue viability, thereby preventing cooling during heat treatment and reducing bleeding during surgery without requiring complete blood flow cessation.
Solution Approach 2:
The balloon stopper unit modifies the blood flow parameter by applying mechanical compression to reduce blood supply to the prostate. This parameter change allows temperature stabilization during heat treatment and reduces bleeding during surgical procedures, resolving the contradiction between temperature control and blood loss prevention.
3Adaptability or versatility
If multiple medications are delivered through separate devices, then comprehensive treatment is possible, but device complexity and operation difficulty increase
Solution Approach 1:
The catheter is designed as a universal multi-functional device that can deliver multiple medications (adrenaline, anesthetic agents, botulinum toxin, penicillin) through a single injection tube and hollow tip system. The drainage lumen and balloon stopper unit provide additional functions for drainage and blood flow control. This multi-functionality resolves the contradiction by enabling comprehensive medication delivery without requiring multiple separate devices, thus reducing operational complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The kit and method effectively reduce perioperative bleeding and enhance treatment efficacy by maintaining adrenaline's effect for up to 15 minutes, allowing for controlled and efficient prostate trimming and heat treatment with reduced blood loss and improved visibility.
Implementation Method 1
filling of the balloon stopper unit with a fluid is intended when the balloon stopper unit is arranged inside of the bladder of a patient to provide for a stopper function of the balloon stopper unit against the bladder neck of the patient
Implementation Method 2
injecting at least one anesthetic agent and adrenaline or injecting botulinum toxin (Botox) and/or penicillin to the prostate via the injection tube and the hollow tip at an intended position of the prostate
Implementation Method 3
maintaining adrenaline's effect for up to 15 minutes, allowing for controlled and efficient prostate trimming and heat treatment with reduced blood loss
Implementation Method 4
an introduction unit with a top, said introduction unit also comprising a drainage lumen hole for drainage of a urinary bladder
